+ <h1 class="title">Apache Accumulo File System Archive Example (Data Only)</h1>
+
+ <p>This example archives file data into an Accumulo table. Files with duplicate data are only stored once.
+The example has the following classes:</p>
+<ul>
+<li>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.</li>
+<li>ChunkCombiner - An Iterator that dedupes file data and sets their visibilities to a combined visibility based on current references to the file data.</li>
+<li>ChunkInputFormat - An Accumulo InputFormat that provides keys containing file info (List<Entry<Key,Value>>) and values with an InputStream over the file (ChunkInputStream).</li>
+<li>ChunkInputStream - An input stream over file data stored in Accumulo.</li>
+<li>FileDataIngest - Takes a list of files and archives them into Accumulo keyed on hashes of the files.</li>
+<li>FileDataQuery - Retrieves file data based on the hash of the file. (Used by the dirlist.Viewer.)</li>
+<li>KeyUtil - A utility for creating and parsing null-byte separated strings into/from Text objects.</li>
+<li>VisibilityCombiner - A utility for merging visibilities into the form (VIS1)|(VIS2)|...</li>
+</ul>
+<p>This example is coupled with the dirlist example. See README.dirlist for instructions.</p>
+<p>If you haven't already run the README.dirlist example, ingest a file with FileDataIngest.</p>

+ <h1 class="title">Apache Accumulo Filter Example</h1>
+
+ <p>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.</p>

+
+<p>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.</p>
+<p>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.</p>
+<p>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.</p>

+<p>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.</p>
+<p>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.</p>

+
+ <p>This tutorial uses the following Java classes, which can be found in org.apache.accumulo.examples.simple.helloworld in the examples-simple module:</p>
+<ul>
+<li>InsertWithBatchWriter.java - Inserts 10K rows (50K entries) into accumulo with each row having 5 entries</li>
+<li>ReadData.java - Reads all data between two rows</li>
+</ul>
+<p>Log into the accumulo shell:</p>
+<div class="codehilite"><pre>$ <span class="o">./</span><span class="n">bin</span><span class="o">/</span><span class="n">accumulo</span> <span class="n">shell</span> <span class="o">-</span><span class="n">u</span> <span class="n">username</span> <span class="o">-</span><span class="n">p</span> <span class="n">password</span>
+</pre></div>
+
+
+<p>Create a table called 'hellotable':</p>
+<div class="codehilite"><pre><span class="n">username</span><span class="p">@</span><span class="n">instance</span><span class="o">></span> <span class="n">createtable</span> <span class="n">hellotable</span>
+</pre></div>
+
+
+<p>Launch a Java program that inserts data with a BatchWriter:</p>
+<div class="codehilite"><pre>$ <span class="o">./</span><span class="n">bin</span><span class="o">/</span><span class="n">accumulo</span> <span class="n">org</span><span class="p">.</span><span class="n">apache</span><span class="p">.</span><span class="n">accumulo</span><span class="p">.</span><span class="n">examples</span><span class="p">.</span><span class="n">simple</span><span class="p">.</span><span class="n">helloworld</span><span class="p">.</span><span class="n">InsertWithBatchWriter</span> <span class="o">-</span><span class="nb">i</span> <span class="n">instance</span> <span class="o">-</span><span class="n">z</span> <span class="n">zookeepers</span> <span class="o">-</span><span class="n">u</span> <span class="n">username</span> <span class="o">-</span><span class="n">p</span> <span class="n">password</span> <span class="o">-</span><span class="n">t</span> <span class="n">hellotable</span>
+</pre></div>
+
+
+<p>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</p>
+<div class="codehilite"><pre><span class="n">http</span><span class="p">:</span><span class="o">//</span><span class="n">master</span><span class="p">:</span>50095<span class="o">/</span>
+</pre></div>
+
+
+<p>To view the entries, use the shell to scan the table:</p>
+<div class="codehilite"><pre><span class="n">username</span><span class="p">@</span><span class="n">instance</span><span class="o">></span> <span class="n">table</span> <span class="n">hellotable</span>
+<span class="n">username</span><span class="p">@</span><span class="n">instance</span> <span class="n">hellotable</span><span class="o">></span> <span class="n">scan</span>
+</pre></div>
+
+
+<p>You can also use a Java class to scan the table:</p>
+<div class="codehilite"><pre>$ <span class="o">./</span><span class="n">bin</span><span class="o">/</span><span class="n">accumulo</span> <span class="n">org</span><span class="p">.</span><span class="n">apache</span><span class="p">.</span><span class="n">accumulo</span><span class="p">.</span><span class="n">examples</span><span class="p">.</span><span class="n">simple</span><span class="p">.</span><span class="n">helloworld</span><span class="p">.</span><span class="n">ReadData</span> <span class="o">-</span><span class="nb">i</span> <span class="n">instance</span> <span class="o">-</span><span class="n">z</span> <span class="n">zookeepers</span> <span class="o">-</span><span class="n">u</span> <span class="n">username</span> <span class="o">-</span><span class="n">p</span> <span class="n">password</span> <span class="o">-</span><span class="n">t</span> <span class="n">hellotable</span> <span class="o">--</span><span class="n">startKey</span> <span class="n">row_0</span> <span cl

+ <h1 class="title">Apache Accumulo Examples</h1>
+
+ <p>Before running any of the examples, the following steps must be performed.</p>
+<ol>
+<li>
+<p>Install and run Accumulo via the instructions found in $ACCUMULO_HOME/README.
+ Remember the instance name. It will be referred to as "instance" throughout
+ the examples. A comma-separated list of zookeeper servers will be referred
+ to as "zookeepers".</p>
+</li>
+<li>
+<p>Create an Accumulo user (see the <a href="/1.6/user_manual/Accumulo_Shell.html#User_Administration">user manual</a>), or use the root user.
+ The "username" Accumulo user name with password "password" is used
+ throughout the examples. This user needs the ability to create tables.</p>
+</li>
+</ol>
+<p>In all commands, you will need to replace "instance", "zookeepers",
+"username", and "password" with the values you set for your Accumulo instance.</p>
+<p>Commands intended to be run in bash are prefixed by '$'. These are always
+assumed to be run from the $ACCUMULO_HOME directory.</p>
+<p>Commands intended to be run in the Accumulo shell are prefixed by '>'.</p>

+features of Apache Accumulo.</p>
