+This tutorial uses the following Java classes, which can be found in org.apache.accumulo.examples.simple.client in the examples-simple module:
+
+ * SequentialBatchWriter.java - writes mutations with sequential rows and random values
+ * RandomBatchWriter.java - used by SequentialBatchWriter to generate random values
+ * RandomBatchScanner.java - reads random rows and verifies their values
+
+This is an example of how to use the batch writer and batch scanner. To compile
+the example, run maven and copy the produced jar into the accumulo lib dir.
+This is already done in the tar distribution.
+
+Below are commands that add 10000 entries to accumulo and then do 100 random
+queries. The write command generates random 50 byte values.
+
+Be sure to use the name of your instance (given as instance here) and the appropriate
+list of zookeeper nodes (given as zookeepers here).
+
+Before you run this, you must ensure that the user you are running has the
+"exampleVis" authorization. (you can set this in the shell with "setauths -u username -s exampleVis")
+
+ $ ./bin/accumulo shell -u root -e "setauths -u username -s exampleVis"
+
+You must also create the table, batchtest1, ahead of time. (In the shell, use "createtable batchtest1")
+
+ $ ./bin/accumulo shell -u username -e "createtable batchtest1"
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.client.SequentialBatchWriter -i instance -z zookeepers -u username -p password -t batchtest1 --start 0 --num 10000 --size 50 --batchMemory 20M --batchLatency 500 --batchThreads 20 --vis exampleVis
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.client.RandomBatchScanner -i instance -z zookeepers -u username -p password -t batchtest1 --num 100 --min 0 --max 10000 --size 50 --scanThreads 20 --auths exampleVis

+
+This example shows how to create a table with bloom filters enabled. It also
+shows how bloom filters increase query performance when looking for values that
+do not exist in a table.
+
+Below table named bloom_test is created and bloom filters are enabled.
+
+ $ ./bin/accumulo shell -u username -p password
+ Shell - Apache Accumulo Interactive Shell
+ - version: 1.5.0
+ - instance name: instance
+ - instance id: 00000000-0000-0000-0000-000000000000
+ -
+ - type 'help' for a list of available commands
+ -
+ username@instance> setauths -u username -s exampleVis
+ username@instance> createtable bloom_test
+ username@instance bloom_test> config -t bloom_test -s table.bloom.enabled=true
+ username@instance bloom_test> exit
+
+Below 1 million random values are inserted into accumulo. The randomly
+generated rows range between 0 and 1 billion. The random number generator is
+initialized with the seed 7.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.client.RandomBatchWriter --seed 7 -i instance -z zookeepers -u username -p password -t bloom_test --num 1000000 --min 0 --max 1000000000 --size 50 --batchMemory 2M --batchLatency 60s --batchThreads 3 --vis exampleVis
+
+Below the table is flushed:
+
+ $ ./bin/accumulo shell -u username -p password -e 'flush -t bloom_test -w'
+ 05 10:40:06,069 [shell.Shell] INFO : Flush of table bloom_test completed.
+
+After the flush completes, 500 random queries are done against the table. The
+same seed is used to generate the queries, therefore everything is found in the
+table.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.client.RandomBatchScanner --seed 7 -i instance -z zookeepers -u username -p password -t bloom_test --num 500 --min 0 --max 1000000000 --size 50 --scanThreads 20 --auths exampleVis
+ Generating 500 random queries...finished
+ 96.19 lookups/sec 5.20 secs
+ num results : 500
+ Generating 500 random queries...finished
+ 102.35 lookups/sec 4.89 secs
+ num results : 500
+
+Below another 500 queries are performed, using a different seed which results
+in nothing being found. In this case the lookups are much faster because of
+the bloom filters.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.client.RandomBatchScanner --seed 8 -i instance -z zookeepers -u username -p password -t bloom_test --num 500 --min 0 --max 1000000000 --size 50 -batchThreads 20 -auths exampleVis
+ Generating 500 random queries...finished
+ 2212.39 lookups/sec 0.23 secs
+ num results : 0
+ Did not find 500 rows
+ Generating 500 random queries...finished
+ 4464.29 lookups/sec 0.11 secs
+ num results : 0
+ Did not find 500 rows
+
+********************************************************************************
+
+Bloom filters can also speed up lookups for entries that exist. In accumulo
+data is divided into tablets and each tablet has multiple map files. Every
+lookup in accumulo goes to a specific tablet where a lookup is done on each
+map file in the tablet. So if a tablet has three map files, lookup performance
+can be three times slower than a tablet with one map file. However if the map
+files contain unique sets of data, then bloom filters can help eliminate map
+files that do not contain the row being looked up. To illustrate this two
+identical tables were created using the following process. One table had bloom
+filters, the other did not. Also the major compaction ratio was increased to
+prevent the files from being compacted into one file.
+
+ * Insert 1 million entries using RandomBatchWriter with a seed of 7
+ * Flush the table using the shell
+ * Insert 1 million entries using RandomBatchWriter with a seed of 8
+ * Flush the table using the shell
+ * Insert 1 million entries using RandomBatchWriter with a seed of 9
+ * Flush the table using the shell
+
+After following the above steps, each table will have a tablet with three map
+files. Flushing the table after each batch of inserts will create a map file.
+Each map file will contain 1 million entries generated with a different seed.
+This is assuming that Accumulo is configured with enough memory to hold 1
+million inserts. If not, then more map files will be created.
+
+The commands for creating the first table without bloom filters are below.
+
+ $ ./bin/accumulo shell -u username -p password

+
+Below 500 lookups are done against the table without bloom filters using random
+NG seed 7. Even though only one map file will likely contain entries for this
+seed, all map files will be interrogated.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.client.RandomBatchScanner --seed 7 -i instance -z zookeepers -u username -p password -t bloom_test1 --num 500 --min 0 --max 1000000000 --size 50 --scanThreads 20 --auths exampleVis

+ Generating 500 random queries...finished
+ 35.33 lookups/sec 14.15 secs
+ num results : 500
+
+Below the same lookups are done against the table with bloom filters. The
+lookups were 2.86 times faster because only one map file was used, even though three
+map files existed.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.client.RandomBatchScanner --seed 7 -i instance -z zookeepers -u username -p password -t bloom_test2 --num 500 --min 0 --max 1000000000 --size 50 -scanThreads 20 --auths exampleVis

+ 99.03 lookups/sec 5.05 secs
+ num results : 500
+ Generating 500 random queries...finished
+ 101.15 lookups/sec 4.94 secs
+ num results : 500
+
+You can verify the table has three files by looking in HDFS. To look in HDFS
+you will need the table ID, because this is used in HDFS instead of the table
+name. The following command will show table ids.
+
+ $ ./bin/accumulo shell -u username -p password -e 'tables -l'
+ accumulo.metadata => !0
+ accumulo.root => +r
+ bloom_test1 => o7
+ bloom_test2 => o8
+ trace => 1
+
+So the table id for bloom_test2 is o8. The command below shows what files this
+table has in HDFS. This assumes Accumulo is at the default location in HDFS.
+
+ $ hadoop fs -lsr /accumulo/tables/o8
+ drwxr-xr-x - username supergroup 0 2012-01-10 14:02 /accumulo/tables/o8/default_tablet
+ -rw-r--r-- 3 username supergroup 52672650 2012-01-10 14:01 /accumulo/tables/o8/default_tablet/F00000dj.rf
+ -rw-r--r-- 3 username supergroup 52436176 2012-01-10 14:01 /accumulo/tables/o8/default_tablet/F00000dk.rf
+ -rw-r--r-- 3 username supergroup 52850173 2012-01-10 14:02 /accumulo/tables/o8/default_tablet/F00000dl.rf
+
+Running the rfile-info command shows that one of the files has a bloom filter
+and its 1.5MB.
+
+ $ ./bin/accumulo rfile-info /accumulo/tables/o8/default_tablet/F00000dj.rf

+This is an example of how to bulk ingest data into accumulo using map reduce.
+
+The following commands show how to run this example. This example creates a
+table called test_bulk which has two initial split points. Then 1000 rows of
+test data are created in HDFS. After that the 1000 rows are ingested into
+accumulo. Then we verify the 1000 rows are in accumulo.

+This example shows how to use per table classpaths. The example leverages a
+test jar which contains a Filter that supresses rows containing "foo". The
+example shows copying the FooFilter.jar into HDFS and then making an Accumulo
+table reference that jar.
+
+
+Execute the following command in the shell.
+
+ $ hadoop fs -copyFromLocal $ACCUMULO_HOME/test/src/test/resources/FooFilter.jar /user1/lib
+
+Execute following in Accumulo shell to setup classpath context
+
+ root@test15> config -s general.vfs.context.classpath.cx1=hdfs://<namenode host>:<namenode port>/user1/lib/[^.].*.jar
+
+Create a table
+
+ root@test15> createtable nofoo
+
+The following command makes this table use the configured classpath context
+
+ root@test15 nofoo> config -t nofoo -s table.classpath.context=cx1
+
+The following command configures an iterator thats in FooFilter.jar
+
+ root@test15 nofoo> setiter -n foofilter -p 10 -scan -minc -majc -class org.apache.accumulo.test.FooFilter
+ Filter accepts or rejects each Key/Value pair
+ ----------> set FooFilter parameter negate, default false keeps k/v that pass accept method, true rejects k/v that pass accept method: false
+
+The commands below show the filter is working.
+
+ root@test15 nofoo> insert foo1 f1 q1 v1
+ root@test15 nofoo> insert noo1 f1 q1 v2
+ root@test15 nofoo> scan
+ noo1 f1:q1 [] v2
+ root@test15 nofoo>
+
+Below, an attempt is made to add the FooFilter to a table thats not configured
+to use the clasppath context cx1. This fails util the table is configured to
+use cx1.
+
+ root@test15 nofoo> createtable nofootwo

+This documents how you run the simplest java examples.
+
+This tutorial uses the following Java classes, which can be found in org.apache.accumulo.examples.simple.client in the examples-simple module:
+
+ * Flush.java - flushes a table
+ * RowOperations.java - reads and writes rows
+ * ReadWriteExample.java - creates a table, writes to it, and reads from it
+
+Using the accumulo command, you can run the simple client examples by providing their
+class name, and enough arguments to find your accumulo instance. For example,
+the Flush class will flush a table:
+
+ $ PACKAGE=org.apache.accumulo.examples.simple.client
+ $ bin/accumulo $PACKAGE.Flush -u root -p mypassword -i instance -z zookeeper -t trace
+
+The very simple RowOperations class demonstrates how to read and write rows using the BatchWriter
+and Scanner:
+
+ $ bin/accumulo $PACKAGE.RowOperations -u root -p mypassword -i instance -z zookeeper

+This tutorial uses the following Java class, which can be found in org.apache.accumulo.examples.simple.combiner in the examples-simple module:
+
+ * StatsCombiner.java - a combiner that calculates max, min, sum, and count
+
+This is a simple combiner example. To build this example run maven and then
+copy the produced jar into the accumulo lib dir. This is already done in the
+tar distribution.

+
+In this example a table is created and the example stats combiner is applied to
+the column family stat and hstat. The stats combiner computes min,max,sum, and
+count. It can be configured to use a different base or radix. In the example
+above the column family stat is configured for base 10 and the column family
+hstat is configured for base 16.

+This example stores filesystem information in accumulo. The example stores the information in the following three tables. More information about the table structures can be found at the end of README.dirlist.
+
+ * directory table : This table stores information about the filesystem directory structure.
+ * index table : This table stores a file name index. It can be used to quickly find files with given name, suffix, or prefix.
+ * data table : This table stores the file data. File with duplicate data are only stored once.
+
+This example shows how to use Accumulo to store a file system history. It has the following classes:
+
+ * Ingest.java - Recursively lists the files and directories under a given path, ingests their names and file info into one Accumulo table, indexes the file names in a separate table, and the file data into a third table.
+ * QueryUtil.java - Provides utility methods for getting the info for a file, listing the contents of a directory, and performing single wild card searches on file or directory names.
+ * Viewer.java - Provides a GUI for browsing the file system information stored in Accumulo.
+ * FileCount.java - Computes recursive counts over file system information and stores them back into the same Accumulo table.
+
+To begin, ingest some data with Ingest.java.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.dirlist.Ingest -i instance -z zookeepers -u username -p password --vis exampleVis --chunkSize 100000 /local/username/workspace
+
+This may take some time if there are large files in the /local/username/workspace directory. If you use 0 instead of 100000 on the command line, the ingest will run much faster, but it will not put any file data into Accumulo (the dataTable will be empty).
+Note that running this example will create tables dirTable, indexTable, and dataTable in Accumulo that you should delete when you have completed the example.
+If you modify a file or add new files in the directory ingested (e.g. /local/username/workspace), you can run Ingest again to add new information into the Accumulo tables.
+
+To browse the data ingested, use Viewer.java. Be sure to give the "username" user the authorizations to see the data (in this case, run
+
+ $ ./bin/accumulo shell -u root -e 'setauths -u username -s exampleVis'
+
+then run the Viewer:
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.dirlist.Viewer -i instance -z zookeepers -u username -p password -t dirTable --dataTable dataTable --auths exampleVis --path /local/username/workspace
+
+To list the contents of specific directories, use QueryUtil.java.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.dirlist.QueryUtil -i instance -z zookeepers -u username -p password -t dirTable --auths exampleVis --path /local/username
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.dirlist.QueryUtil -i instance -z zookeepers -u username -p password -t dirTable --auths exampleVis --path /local/username/workspace
+
+To perform searches on file or directory names, also use QueryUtil.java. Search terms must contain no more than one wild card and cannot contain "/".
+*Note* these queries run on the _indexTable_ table instead of the dirTable table.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.dirlist.QueryUtil -i instance -z zookeepers -u username -p password -t indexTable --auths exampleVis --path filename --search
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.dirlist.QueryUtil -i instance -z zookeepers -u username -p password -t indexTable --auths exampleVis --path 'filename*' --search
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.dirlist.QueryUtil -i instance -z zookeepers -u username -p password -t indexTable --auths exampleVis --path '*jar' --search
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.dirlist.QueryUtil -i instance -z zookeepers -u username -p password -t indexTable --auths exampleVis --path 'filename*jar' --search
+
+To count the number of direct children (directories and files) and descendants (children and children's descendants, directories and files), run the FileCount over the dirTable table.
+The results are written back to the same table. FileCount reads from and writes to Accumulo. This requires scan authorizations for the read and a visibility for the data written.
+In this example, the authorizations and visibility are set to the same value, exampleVis. See README.visibility for more information on visibility and authorizations.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.dirlist.FileCount -i instance -z zookeepers -u username -p password -t dirTable --auths exampleVis
+
+## Directory Table
+
+Here is a illustration of what data looks like in the directory table:
+
+ row colf:colq [vis] value
+ 000 dir:exec [exampleVis] true
+ 000 dir:hidden [exampleVis] false
+ 000 dir:lastmod [exampleVis] 1291996886000
+ 000 dir:length [exampleVis] 1666
+ 001/local dir:exec [exampleVis] true
+ 001/local dir:hidden [exampleVis] false
+ 001/local dir:lastmod [exampleVis] 1304945270000
+ 001/local dir:length [exampleVis] 272
+ 002/local/Accumulo.README \x7F\xFF\xFE\xCFH\xA1\x82\x97:exec [exampleVis] false
+ 002/local/Accumulo.README \x7F\xFF\xFE\xCFH\xA1\x82\x97:hidden [exampleVis] false
+ 002/local/Accumulo.README \x7F\xFF\xFE\xCFH\xA1\x82\x97:lastmod [exampleVis] 1308746481000
+ 002/local/Accumulo.README \x7F\xFF\xFE\xCFH\xA1\x82\x97:length [exampleVis] 9192
+ 002/local/Accumulo.README \x7F\xFF\xFE\xCFH\xA1\x82\x97:md5 [exampleVis] 274af6419a3c4c4a259260ac7017cbf1
+
+The rows are of the form depth + path, where depth is the number of slashes ("/") in the path padded to 3 digits. This is so that all the children of a directory appear as consecutive keys in Accumulo; without the depth, you would for example see all the subdirectories of /local before you saw /usr.
+For directories the column family is "dir". For files the column family is Long.MAX_VALUE - lastModified in bytes rather than string format so that newer versions sort earlier.
+
+## Index Table
+
+Here is an illustration of what data looks like in the index table:
+
+ row colf:colq [vis]
+ fAccumulo.README i:002/local/Accumulo.README [exampleVis]
+ flocal i:001/local [exampleVis]
+ rEMDAER.olumuccA i:002/local/Accumulo.README [exampleVis]
+ rlacol i:001/local [exampleVis]
+
+The values of the index table are null. The rows are of the form "f" + filename or "r" + reverse file name. This is to enable searches with wildcards at the beginning, middle, or end.
+
+## Data Table
+
+Here is an illustration of what data looks like in the data table:
+
+ row colf:colq [vis] value
+ 274af6419a3c4c4a259260ac7017cbf1 refs:e77276a2b56e5c15b540eaae32b12c69\x00filext [exampleVis] README

+ 274af6419a3c4c4a259260ac7017cbf1 ~chunk:\x00\x0FB@\x00\x00\x00\x00 [exampleVis] *******************************************************************************\x0A1. Building\x0A\x0AIn the normal tarball release of accumulo, [truncated]
+ 274af6419a3c4c4a259260ac7017cbf1 ~chunk:\x00\x0FB@\x00\x00\x00\x01 [exampleVis]
+
+The rows are the md5 hash of the file. Some column family : column qualifier pairs are "refs" : hash of file name + null byte + property name, in which case the value is property value. There can be multiple references to the same file which are distinguished by the hash of the file name.
+Other column family : column qualifier pairs are "~chunk" : chunk size in bytes + chunk number in bytes, in which case the value is the bytes for that chunk of the file. There is an end of file data marker whose chunk number is the number of chunks for the file and whose value is empty.
+
+There may exist multiple copies of the same file (with the same md5 hash) with different chunk sizes or different visibilities. There is an iterator that can be set on the data table that combines these copies into a single copy with a visibility taken from the visibilities of the file references, e.g. (vis from ref1)|(vis from ref2).

+Accumulo provides a mechanism to export and import tables. This README shows
+how to use this feature.
+
+The shell session below shows creating a table, inserting data, and exporting
+the table. A table must be offline to export it, and it should remain offline
+for the duration of the distcp. An easy way to take a table offline without
+interuppting access to it is to clone it and take the clone offline.
+
+ root@test15> createtable table1
+ root@test15 table1> insert a cf1 cq1 v1
+ root@test15 table1> insert h cf1 cq1 v2
+ root@test15 table1> insert z cf1 cq1 v3
+ root@test15 table1> insert z cf1 cq2 v4
+ root@test15 table1> addsplits -t table1 b r
+ root@test15 table1> scan
+ a cf1:cq1 [] v1
+ h cf1:cq1 [] v2
+ z cf1:cq1 [] v3

+ root@test15 table1> offline table1_exp
+ root@test15 table1> exporttable -t table1_exp /tmp/table1_export
+ root@test15 table1> quit
+
+After executing the export command, a few files are created in the hdfs dir.
+One of the files is a list of files to distcp as shown below.
+

+This example archives file data into an Accumulo table. Files with duplicate data are only stored once.
+The example has the following classes:
+
+ * CharacterHistogram - A MapReduce that computes a histogram of byte frequency for each file and stores the histogram alongside the file data. An example use of the ChunkInputFormat.
+ * ChunkCombiner - An Iterator that dedupes file data and sets their visibilities to a combined visibility based on current references to the file data.
+ * ChunkInputFormat - An Accumulo InputFormat that provides keys containing file info (List<Entry<Key,Value>>) and values with an InputStream over the file (ChunkInputStream).
+ * ChunkInputStream - An input stream over file data stored in Accumulo.
+ * FileDataIngest - Takes a list of files and archives them into Accumulo keyed on hashes of the files.
+ * FileDataQuery - Retrieves file data based on the hash of the file. (Used by the dirlist.Viewer.)
+ * KeyUtil - A utility for creating and parsing null-byte separated strings into/from Text objects.
+ * VisibilityCombiner - A utility for merging visibilities into the form (VIS1)|(VIS2)|...
+
+This example is coupled with the dirlist example. See README.dirlist for instructions.
+
+If you haven't already run the README.dirlist example, ingest a file with FileDataIngest.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.filedata.FileDataIngest -i instance -z zookeepers -u username -p password -t dataTable --auths exampleVis --chunk 1000 $ACCUMULO_HOME/README
+
+Open the accumulo shell and look at the data. The row is the MD5 hash of the file, which you can verify by running a command such as 'md5sum' on the file.
+
+ > scan -t dataTable
+
+Run the CharacterHistogram MapReduce to add some information about the file.
+
+ $ bin/tool.sh lib/accumulo-examples-simple.jar org.apache.accumulo.examples.simple.filedata.CharacterHistogram -i instance -z zookeepers -u username -p password -t dataTable --auths exampleVis --vis exampleVis

+
+This is a simple filter example. It uses the AgeOffFilter that is provided as
+part of the core package org.apache.accumulo.core.iterators.user. Filters are
+iterators that select desired key/value pairs (or weed out undesired ones).
+Filters extend the org.apache.accumulo.core.iterators.Filter class
+and must implement a method accept(Key k, Value v). This method returns true
+if the key/value pair are to be delivered and false if they are to be ignored.
+Filter takes a "negate" parameter which defaults to false. If set to true, the
+return value of the accept method is negated, so that key/value pairs accepted
+by the method are omitted by the Filter.
+
+ username@instance> createtable filtertest
+ username@instance filtertest> setiter -t filtertest -scan -p 10 -n myfilter -ageoff
+ AgeOffFilter removes entries with timestamps more than <ttl> milliseconds old
+ ----------> set AgeOffFilter parameter negate, default false keeps k/v that pass accept method, true rejects k/v that pass accept method:
+ ----------> set AgeOffFilter parameter ttl, time to live (milliseconds): 30000
+ ----------> set AgeOffFilter parameter currentTime, if set, use the given value as the absolute time in milliseconds as the current time of day:
+ username@instance filtertest> scan
+ username@instance filtertest> insert foo a b c
+ username@instance filtertest> scan
+ foo a:b [] c
+ username@instance filtertest>
+
+... wait 30 seconds ...
+
+ username@instance filtertest> scan
+ username@instance filtertest>
+
+Note the absence of the entry inserted more than 30 seconds ago. Since the
+scope was set to "scan", this means the entry is still in Accumulo, but is
+being filtered out at query time. To delete entries from Accumulo based on
+the ages of their timestamps, AgeOffFilters should be set up for the "minc"
+and "majc" scopes, as well.
+
+To force an ageoff of the persisted data, after setting up the ageoff iterator
+on the "minc" and "majc" scopes you can flush and compact your table. This will
+happen automatically as a background operation on any table that is being
+actively written to, but can also be requested in the shell.
+
+The first setiter command used the special -ageoff flag to specify the
+AgeOffFilter, but any Filter can be configured by using the -class flag. The
+following commands show how to enable the AgeOffFilter for the minc and majc
+scopes using the -class flag, then flush and compact the table.
+
+ username@instance filtertest> setiter -t filtertest -minc -majc -p 10 -n myfilter -class org.apache.accumulo.core.iterators.user.AgeOffFilter
+ AgeOffFilter removes entries with timestamps more than <ttl> milliseconds old
+ ----------> set AgeOffFilter parameter negate, default false keeps k/v that pass accept method, true rejects k/v that pass accept method:
+ ----------> set AgeOffFilter parameter ttl, time to live (milliseconds): 30000
+ ----------> set AgeOffFilter parameter currentTime, if set, use the given value as the absolute time in milliseconds as the current time of day:
+ username@instance filtertest> flush
+ 06 10:42:24,806 [shell.Shell] INFO : Flush of table filtertest initiated...
+ username@instance filtertest> compact
+ 06 10:42:36,781 [shell.Shell] INFO : Compaction of table filtertest started for given range
+ username@instance filtertest> flush -t filtertest -w
+ 06 10:42:52,881 [shell.Shell] INFO : Flush of table filtertest completed.
+ username@instance filtertest> compact -t filtertest -w
+ 06 10:43:00,632 [shell.Shell] INFO : Compacting table ...
+ 06 10:43:01,307 [shell.Shell] INFO : Compaction of table filtertest completed for given range
+ username@instance filtertest>
+
+By default, flush and compact execute in the background, but with the -w flag
+they will wait to return until the operation has completed. Both are
+demonstrated above, though only one call to each would be necessary. A
+specific table can be specified with -t.
+
+After the compaction runs, the newly created files will not contain any data
+that should have been aged off, and the Accumulo garbage collector will remove
+the old files.
+
+To see the iterator settings for a table, use config.
+
+ username@instance filtertest> config -t filtertest -f iterator

+This tutorial uses the following Java classes, which can be found in org.apache.accumulo.examples.simple.helloworld in the examples-simple module:
+
+ * InsertWithBatchWriter.java - Inserts 10K rows (50K entries) into accumulo with each row having 5 entries
+ * ReadData.java - Reads all data between two rows
+
+Log into the accumulo shell:
+
+ $ ./bin/accumulo shell -u username -p password
+
+Create a table called 'hellotable':
+
+ username@instance> createtable hellotable
+
+Launch a Java program that inserts data with a BatchWriter:
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.helloworld.InsertWithBatchWriter -i instance -z zookeepers -u username -p password -t hellotable
+
+On the accumulo status page at the URL below (where 'master' is replaced with the name or IP of your accumulo master), you should see 50K entries
+
+ http://master:9995/
+
+To view the entries, use the shell to scan the table:
+
+ username@instance> table hellotable
+ username@instance hellotable> scan
+
+You can also use a Java class to scan the table:
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.helloworld.ReadData -i instance -z zookeepers -u username -p password -t hellotable --startKey row_0 --endKey row_1001

+
+Before running any of the examples, the following steps must be performed.
+
+1. Install and run Accumulo via the instructions found in $ACCUMULO_HOME/README.
+ Remember the instance name. It will be referred to as "instance" throughout
+ the examples. A comma-separated list of zookeeper servers will be referred
+ to as "zookeepers".
+
+2. Create an Accumulo user (see the [user manual][1]), or use the root user.
+ The "username" Accumulo user name with password "password" is used
+ throughout the examples. This user needs the ability to create tables.
+
+In all commands, you will need to replace "instance", "zookeepers",
+"username", and "password" with the values you set for your Accumulo instance.
+
+Commands intended to be run in bash are prefixed by '$'. These are always
+assumed to be run from the $ACCUMULO_HOME directory.
+
+Commands intended to be run in the Accumulo shell are prefixed by '>'.
+
+Each README in the examples directory highlights the use of particular
+features of Apache Accumulo.

+
+Accumulo has an isolated scanner that ensures partial changes to rows are not
+seen. Isolation is documented in ../docs/isolation.html and the user manual.
+
+InterferenceTest is a simple example that shows the effects of scanning with
+and without isolation. This program starts two threads. One threads
+continually upates all of the values in a row to be the same thing, but
+different from what it used to be. The other thread continually scans the
+table and checks that all values in a row are the same. Without isolation the
+scanning thread will sometimes see different values, which is the result of
+reading the row at the same time a mutation is changing the row.
+
+Below, Interference Test is run without isolation enabled for 5000 iterations
+and it reports problems.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.isolation.InterferenceTest -i instance -z zookeepers -u username -p password -t isotest --iterations 5000

+This example uses mapreduce and accumulo to compute word counts for a set of
+documents. This is accomplished using a map-only mapreduce job and a
+accumulo table with combiners.
+
+To run this example you will need a directory in HDFS containing text files.
+The accumulo readme will be used to show how to run this example.

+
+After creating the table, run the word count map reduce job.
+

+
+After the map reduce job completes, query the accumulo table to see word
+counts.
+
+ $ ./bin/accumulo shell -u username -p password
+ username@instance> table wordCount
+ username@instance wordCount> scan -b the
+ the count:20080906 [] 75

+
+Another example to look at is
+org.apache.accumulo.examples.simple.mapreduce.UniqueColumns. This example
+computes the unique set of columns in a table and shows how a map reduce job
+can directly read a tables files from HDFS.
+
+One more example available is
+org.apache.accumulo.examples.simple.mapreduce.TokenFileWordCount.
+The TokenFileWordCount example works exactly the same as the WordCount example
+explained above except that it uses a token file rather than giving the
+password directly to the map-reduce job (this avoids having the password
+displayed in the job's configuration which is world-readable).
+
+To create a token file, use the create-token utility
+
+ $ ./bin/accumulo create-token
+
+It defaults to creating a PasswordToken, but you can specify the token class
+with -tc (requires the fully qualified class name). Based on the token class,
+it will prompt you for each property required to create the token.
+
+The last value it prompts for is a local filename to save to. If this file
+exists, it will append the new token to the end. Multiple tokens can exist in
+a file, but only the first one for each user will be recognized.
+
+Rather than waiting for the prompts, you can specify some options when calling
+create-token, for example
+
+ $ ./bin/accumulo create-token -u root -p secret -f root.pw
+
+would create a token file containing a PasswordToken for
+user 'root' with password 'secret' and saved to 'root.pw'
+
+This local file needs to be uploaded to hdfs to be used with the
+map-reduce job. For example, if the file were 'root.pw' in the local directory:
+
+ $ hadoop fs -put root.pw root.pw
+
+This would put 'root.pw' in the user's home directory in hdfs.
+
+Because the basic WordCount example uses Opts to parse its arguments
+(which extends ClientOnRequiredTable), you can use a token file with
+the basic WordCount example by calling the same command as explained above
+except replacing the password with the token file (rather than -p, use -tf).
+
+ $ ./bin/tool.sh lib/accumulo-examples-simple.jar org.apache.accumulo.examples.simple.mapreduce.WordCount -i instance -z zookeepers --input /user/username/wc -t wordCount -u username -tf tokenfile
+
+In the above examples, username was 'root' and tokenfile was 'root.pw'
+
+However, if you don't want to use the Opts class to parse arguments,
+the TokenFileWordCount is an example of using the token file manually.
+
+ $ bin/tool.sh lib/accumulo-examples-simple.jar org.apache.accumulo.examples.simple.mapreduce.TokenFileWordCount instance zookeepers username tokenfile /user/username/wc wordCount
+
+The results should be the same as the WordCount example except that the
+authentication token was not stored in the configuration. It was instead
+stored in a file that the map-reduce job pulled into the distributed cache.
+(If you ran either of these on the same table right after the
+WordCount example, then the resulting counts should just double.)

+
+This an example of how to limit the size of mutations that will be accepted into
+a table. Under the default configuration, accumulo does not provide a limitation
+on the size of mutations that can be ingested. Poorly behaved writers might
+inadvertently create mutations so large, that they cause the tablet servers to
+run out of memory. A simple contraint can be added to a table to reject very
+large mutations.
+
+ $ ./bin/accumulo shell -u username -p password
+
+ Shell - Apache Accumulo Interactive Shell
+ -
+ - version: 1.5.0
+ - instance name: instance
+ - instance id: 00000000-0000-0000-0000-000000000000

+ username@instance test_ingest> config -t test_ingest -s table.constraint.1=org.apache.accumulo.examples.simple.constraints.MaxMutationSize
+ username@instance test_ingest>
+
+
+Now the table will reject any mutation that is larger than 1/256th of the
+working memory of the tablet server. The following command attempts to ingest
+a single row with 10000 columns, which exceeds the memory limit. Depending on the
+amount of Java heap your tserver(s) are given, you may have to increase the number
+of columns provided to see the failure.
+
+ $ ./bin/accumulo org.apache.accumulo.test.TestIngest -i instance -z zookeepers -u username -p password --rows 1 --cols 10000

+This example uses mapreduce and accumulo to find items using regular expressions.
+This is accomplished using a map-only mapreduce job and a scan-time iterator.
+
+To run this example you will need some data in a table. The following will
+put a trivial amount of data into accumulo using the accumulo shell:
+
+ $ ./bin/accumulo shell -u username -p password
+ Shell - Apache Accumulo Interactive Shell
+ - version: 1.5.0
+ - instance name: instance
+ - instance id: 00000000-0000-0000-0000-000000000000
+ -

+ -
+ username@instance> createtable input
+ username@instance> insert dogrow dogcf dogcq dogvalue
+ username@instance> insert catrow catcf catcq catvalue
+ username@instance> quit
+
+The RegexExample class sets an iterator on the scanner. This does pattern matching
+against each key/value in accumulo, and only returns matching items. It will do this
+in parallel and will store the results in files in hdfs.
+
+The following will search for any rows in the input table that starts with "dog":
+
+ $ bin/tool.sh lib/accumulo-examples-simple.jar org.apache.accumulo.examples.simple.mapreduce.RegexExample -u user -p passwd -i instance -t input --rowRegex 'dog.*' --output /tmp/output
+

+ -rw-r--r-- 1 username supergroup 51 2013-01-10 14:10 /tmp/output/part-m-00000
+
+We can see the output of our little map-reduce job:

+This example shows running a simple reservation system implemented using
+conditional mutations. This system guarantees that only one concurrent user can
+reserve a resource. The example's reserve command allows multiple users to be
+specified. When this is done, it creates a separate reservation thread for each
+user. In the example below threads are spun up for alice, bob, eve, mallory,
+and trent to reserve room06 on 20140101. Bob ends up getting the reservation
+and everyone else is put on a wait list. The example code will take any string
+for what, when and who.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.reservations.ARS
+ >connect test16 localhost root secret ars
+ connected
+ >
+ Commands :
+ reserve <what> <when> <who> {who}
+ cancel <what> <when> <who>
+ list <what> <when>
+ >reserve room06 20140101 alice bob eve mallory trent
+ bob : RESERVED
+ mallory : WAIT_LISTED
+ alice : WAIT_LISTED
+ trent : WAIT_LISTED
+ eve : WAIT_LISTED
+ >list room06 20140101
+ Reservation holder : bob
+ Wait list : [mallory, alice, trent, eve]
+ >cancel room06 20140101 alice
+ >cancel room06 20140101 bob
+ >list room06 20140101
+ Reservation holder : mallory
+ Wait list : [trent, eve]
+ >quit
+
+Scanning the table in the Accumulo shell after running the example shows the
+following:
+
+ root@test16> table ars
+ root@test16 ars> scan
+ room06:20140101 res:0001 [] mallory
+ room06:20140101 res:0003 [] trent
+ room06:20140101 res:0004 [] eve
+ room06:20140101 tx:seq [] 6
+
+The tx:seq column is incremented for each update to the row allowing for
+detection of concurrent changes. For an update to go through, the sequence
+number must not have changed since the data was read. If it does change,
+the conditional mutation will fail and the example code will retry.

+For some data access patterns, its important to spread groups of tablets within
+a table out evenly. Accumulo has a balancer that can do this using a regular
+expression to group tablets. This example shows how this balancer spreads 4
+groups of tablets within a table evenly across 17 tablet servers.
+
+Below shows creating a table and adding splits. For this example we would like
+all of the tablets where the split point has the same two digits to be on
+different tservers. This gives us four groups of tablets: 01, 02, 03, and 04.
+

+Below the information above was massaged to show which tablet groups are on
+each tserver. The four tablets in group 03 are on two tservers, ideally those
+tablets would be spread across 4 tservers. Note the default tablet (2<) was
+categorized as group 04 below.

+
+To remedy this situation, the RegexGroupBalancer is configured with the
+commands below. The configured regular expression selects the first two digits
+from a tablets end row as the group id. Tablets that don't match and the
+default tablet are configured to be in group 04.
+
+ root@accumulo testRGB> config -t testRGB -s table.custom.balancer.group.regex.pattern=(\\d\\d).*

+
+If you need this functionality, but a regular expression does not meet your
+needs then extend GroupBalancer. This allows you to specify a partitioning
+function in Java. Use the RegexGroupBalancer source as an example.

+
+Basic Sampling Example
+----------------------
+
+Accumulo supports building a set of sample data that can be efficiently
+accessed by scanners. What data is included in the sample set is configurable.
+Below, some data representing documents are inserted.
+
+ root@instance sampex> createtable sampex
+ root@instance sampex> insert 9255 doc content 'abcde'
+ root@instance sampex> insert 9255 doc url file://foo.txt
+ root@instance sampex> insert 8934 doc content 'accumulo scales'
+ root@instance sampex> insert 8934 doc url file://accumulo_notes.txt
+ root@instance sampex> insert 2317 doc content 'milk, eggs, bread, parmigiano-reggiano'
+ root@instance sampex> insert 2317 doc url file://groceries/9.txt
+ root@instance sampex> insert 3900 doc content 'EC2 ate my homework'
+ root@instance sampex> insert 3900 doc uril file://final_project.txt
+
+Below the table sampex is configured to build a sample set. The configuration
+causes Accumulo to include any row where `murmur3_32(row) % 3 ==0` in the
+tables sample data.
+
+ root@instance sampex> config -t sampex -s table.sampler.opt.hasher=murmur3_32
+ root@instance sampex> config -t sampex -s table.sampler.opt.modulus=3
+ root@instance sampex> config -t sampex -s table.sampler=org.apache.accumulo.core.client.sample.RowSampler
+
+Below, attempting to scan the sample returns an error. This is because data
+was inserted before the sample set was configured.
+
+ root@instance sampex> scan --sample
+ 2015-09-09 12:21:50,643 [shell.Shell] ERROR: org.apache.accumulo.core.client.SampleNotPresentException: Table sampex(ID:2) does not have sampling configured or built
+
+To remedy this problem, the following command will flush in memory data and
+compact any files that do not contain the correct sample data.
+
+ root@instance sampex> compact -t sampex --sf-no-sample
+
+After the compaction, the sample scan works.
+
+ root@instance sampex> scan --sample
+ 2317 doc:content [] milk, eggs, bread, parmigiano-reggiano
+ 2317 doc:url [] file://groceries/9.txt
+
+The commands below show that updates to data in the sample are seen when
+scanning the sample.
+
+ root@instance sampex> insert 2317 doc content 'milk, eggs, bread, parmigiano-reggiano, butter'
+ root@instance sampex> scan --sample
+ 2317 doc:content [] milk, eggs, bread, parmigiano-reggiano, butter
+ 2317 doc:url [] file://groceries/9.txt
+
+Inorder to make scanning the sample fast, sample data is partitioned as data is
+written to Accumulo. This means if the sample configuration is changed, that
+data written previously is partitioned using a different criteria. Accumulo
+will detect this situation and fail sample scans. The commands below show this
+failure and fixiing the problem with a compaction.
+
+ root@instance sampex> config -t sampex -s table.sampler.opt.modulus=2
+ root@instance sampex> scan --sample
+ 2015-09-09 12:22:51,058 [shell.Shell] ERROR: org.apache.accumulo.core.client.SampleNotPresentException: Table sampex(ID:2) does not have sampling configured or built
+ root@instance sampex> compact -t sampex --sf-no-sample
+ 2015-09-09 12:23:07,242 [shell.Shell] INFO : Compaction of table sampex started for given range
+ root@instance sampex> scan --sample
+ 2317 doc:content [] milk, eggs, bread, parmigiano-reggiano
+ 2317 doc:url [] file://groceries/9.txt
+ 3900 doc:content [] EC2 ate my homework
+ 3900 doc:uril [] file://final_project.txt
+ 9255 doc:content [] abcde
+ 9255 doc:url [] file://foo.txt
+
+The example above is replicated in a java program using the Accumulo API.
+Below is the program name and the command to run it.
+
+ ./bin/accumulo org.apache.accumulo.examples.simple.sample.SampleExample -i instance -z localhost -u root -p secret
+
+The commands below look under the hood to give some insight into how this
+feature works. The commands determine what files the sampex table is using.
+
+ root@instance sampex> tables -l
+ accumulo.metadata => !0
+ accumulo.replication => +rep
+ accumulo.root => +r
+ sampex => 2
+ trace => 1
+ root@instance sampex> scan -t accumulo.metadata -c file -b 2 -e 2<
+ 2< file:hdfs://localhost:10000/accumulo/tables/2/default_tablet/A000000s.rf [] 702,8
+
+Below shows running `accumulo rfile-info` on the file above. This shows the
+rfile has a normal default locality group and a sample default locality group.
+The output also shows the configuration used to create the sample locality
+group. The sample configuration within a rfile must match the tables sample
+configuration for sample scan to work.
+
+ $ ./bin/accumulo rfile-info hdfs://localhost:10000/accumulo/tables/2/default_tablet/A000000s.rf

+
+Shard Sampling Example
+-------------------------
+
+`README.shard` shows how to index and search files using Accumulo. That
+example indexes documents into a table named `shard`. The indexing scheme used
+in that example places the document name in the column qualifier. A useful
+sample of this indexing scheme should contain all data for any document in the
+sample. To accomplish this, the following commands build a sample for the
+shard table based on the column qualifier.
+
+ root@instance shard> config -t shard -s table.sampler.opt.hasher=murmur3_32
+ root@instance shard> config -t shard -s table.sampler.opt.modulus=101
+ root@instance shard> config -t shard -s table.sampler.opt.qualifier=true
+ root@instance shard> config -t shard -s table.sampler=org.apache.accumulo.core.client.sample.RowColumnSampler
+ root@instance shard> compact -t shard --sf-no-sample -w
+ 2015-07-23 15:00:09,280 [shell.Shell] INFO : Compacting table ...
+ 2015-07-23 15:00:10,134 [shell.Shell] INFO : Compaction of table shard completed for given range
+
+After enabling sampling, the command below counts the number of documents in
+the sample containing the words `import` and `int`.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.shard.Query --sample -i instance16 -z localhost -t shard -u root -p secret import int | fgrep '.java' | wc
+ 11 11 1246
+
+The command below counts the total number of documents containing the words
+`import` and `int`.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.shard.Query -i instance16 -z localhost -t shard -u root -p secret import int | fgrep '.java' | wc
+ 1085 1085 118175
+
+The counts 11 out of 1085 total are around what would be expected for a modulus
+of 101. Querying the sample first provides a quick way to estimate how much data
+the real query will bring back.
+
+Another way sample data could be used with the shard example is with a
+specialized iterator. In the examples source code there is an iterator named
+CutoffIntersectingIterator. This iterator first checks how many documents are
+found in the sample data. If too many documents are found in the sample data,
+then it returns nothing. Otherwise it proceeds to query the full data set.
+To experiment with this iterator, use the following command. The
+`--sampleCutoff` option below will cause the query to return nothing if based
+on the sample it appears a query would return more than 1000 documents.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.shard.Query --sampleCutoff 1000 -i instance16 -z localhost -t shard -u root -p secret import int | fgrep '.java' | wc

+Accumulo has an iterator called the intersecting iterator which supports querying a term index that is partitioned by
+document, or "sharded". This example shows how to use the intersecting iterator through these four programs:
+
+ * Index.java - Indexes a set of text files into an Accumulo table
+ * Query.java - Finds documents containing a given set of terms.
+ * Reverse.java - Reads the index table and writes a map of documents to terms into another table.
+ * ContinuousQuery.java Uses the table populated by Reverse.java to select N random terms per document. Then it continuously and randomly queries those terms.
+
+To run these example programs, create two tables like below.
+
+ username@instance> createtable shard
+ username@instance shard> createtable doc2term
+
+After creating the tables, index some files. The following command indexes all of the java files in the Accumulo source code.
+
+ $ cd /local/username/workspace/accumulo/
+ $ find core/src server/src -name "*.java" | xargs ./bin/accumulo org.apache.accumulo.examples.simple.shard.Index -i instance -z zookeepers -t shard -u username -p password --partitions 30
+
+The following command queries the index to find all files containing 'foo' and 'bar'.
+
+ $ cd $ACCUMULO_HOME
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.shard.Query -i instance -z zookeepers -t shard -u username -p password foo bar

+ /local/username/workspace/accumulo/src/server/src/test/java/accumulo/server/tabletserver/InMemoryMapTest.java
+
+In order to run ContinuousQuery, we need to run Reverse.java to populate doc2term.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.shard.Reverse -i instance -z zookeepers --shardTable shard --doc2Term doc2term -u username -p password
+
+Below ContinuousQuery is run using 5 terms. So it selects 5 random terms from each document, then it continually
+randomly selects one set of 5 terms and queries. It prints the number of matching documents and the time in seconds.
+
+ $ ./bin/accumulo org.apache.accumulo.examples.simple.shard.ContinuousQuery -i instance -z zookeepers --shardTable shard --doc2Term doc2term -u username -p password --terms 5

+This example uses mapreduce to extract specified columns from an existing table.
+
+To run this example you will need some data in a table. The following will
+put a trivial amount of data into accumulo using the accumulo shell:
+
+ $ ./bin/accumulo shell -u username -p password
+ Shell - Apache Accumulo Interactive Shell
+ - version: 1.5.0
+ - instance name: instance
+ - instance id: 00000000-0000-0000-0000-000000000000

+ -
+ username@instance> createtable input
+ username@instance> insert dog cf cq dogvalue
+ username@instance> insert cat cf cq catvalue
+ username@instance> insert junk family qualifier junkvalue
+ username@instance> quit
+
+The TableToFile class configures a map-only job to read the specified columns and
+write the key/value pairs to a file in HDFS.
+
+The following will extract the rows containing the column "cf:cq":
+
+ $ bin/tool.sh lib/accumulo-examples-simple.jar org.apache.accumulo.examples.simple.mapreduce.TableToFile -u user -p passwd -i instance -t input --columns cf:cq --output /tmp/output

+This example uses map/reduce to generate random input data that will
+be sorted by storing it into accumulo. It uses data very similar to the

## Notable Changes
### Deprecated ClientConfiguration API using commons config
-In [ACCUMULO-4611], public API in ClientConfiguration using commons config types was deprecated to
-better support Hadoop 3 in the future. New methods were added to replace these methods which cause
-this release to be a 1.9.0 release. These changes allow removal of commons config from Accumulo's
-API in 2.0.0. If using ClientConfiguration, then switching from existing constructors to the new
-static methods [create()], [fromFile()], or [fromMap()] will ensure your code works in 2.0.0.
