+title: "Apache Drill 1.0.0 Release Notes"
+parent: "Release Notes"
+---
+**Release date:** May 19, 2015
+
+Today we're happy to announce the availability of Drill 1.0.0, providing additional enhancements and bug fixes. This release includes the following new features, enhancements, unresolved issues, and bug fixes:
+
+<h2> Sub-task
+</h2>
+<ul>
+<li>[<a href='https://issues.apache.org/jira/browse/DRILL-2150'>DRILL-2150</a>] - Create an abstraction for repeated value vectors.
+</li>
+<li>[<a href='https://issues.apache.org/jira/browse/DRILL-2358'>DRILL-2358</a>] - Ensure DrillScanRel differentiates skip-all, scan-all & scan-some in a backward compatible fashion
+</li>
+<li>[<a href='https://issues.apache.org/jira/browse/DRILL-2893'>DRILL-2893</a>] - ScanBatch throws a NullPointerException instead of returning OUT_OF_MEMORY
+</li>
+<li>[<a href='https://issues.apache.org/jira/browse/DRILL-2895'>DRILL-2895</a>] - AbstractRecordBatch.buildSchema() should properly handle OUT_OF_MEMORY outcome
+</li>
+<li>[<a href='https://issues.apache.org/jira/browse/DRILL-2902'>DRILL-2902</a>] - Add support for context UDFs: user (and its synonyms session_user, system_user) and current_schema
+</li>
+<li>[<a href='https://issues.apache.org/jira/browse/DRILL-2905'>DRILL-2905</a>] - RootExec implementations should properly handle IterOutcome.OUT_OF_MEMORY
+</li>
+<li>[<a href='https://issues.apache.org/jira/browse/DRILL-2920'>DRILL-2920</a>] - properly handle OutOfMemoryException
+</li>
+<li>[<a href='https://issues.apache.org/jira/browse/DRILL-2947'>DRILL-2947</a>] - AllocationHelper.allocateNew() doesn't have a consistent behavior when it can't allocate
+</li>
+</ul>
+
+<h2> Unresolved Issues
+</h2>
+<ul>
+ <li>[<a href='https://issues.apache.org/jira/browse/DRILL-1868'>DRILL-1868</a>] Aliases are not allowed in WHERE, HAVING and GROUP BY clauses. Drill should return an error when such aliases are encountered, but instead Drill returns an incorrect result.
+ </li>
+ <li>[<a href='https://issues.apache.org/jira/browse/DRILL-2015'>DRILL-2015</a>] Casting a numeric value that does not fit the data type of the value and causes overflow returns an incorrect result.
+ </li>
+ <li>[<a href='https://issues.apache.org/jira/browse/DRILL-2355'>DRILL-2355</a>] Drill output from the TRUNC function in some cases includes an extra .0 in the result. Drill binds TRUNC functions having two input parameters to the function holder. The output type of TRUNC functions is FLOAT8 when the input is FLOAT8, resulting in the extra .0.
+ </li>
+</ul>
+<h2> Bug Fixes
+</h2>
+<ul>

+</li>
+<li>[<a href='https://issues.apache.org/jira/browse/DRILL-708'>DRILL-708</a>] - TRUNC(n1) function returns a decimal instead of int
+</li>
+<li>[<a href='https://issues.apache.org/jira/browse/DRILL-994'>DRILL-994</a>] - Reduce hbase timeout when it is not reachable
+</li>

+title: "Apache Drill 0.9.0 Release Notes"
+parent: "Release Notes"
+---
+It has been about a month since the release of Drill 0.8, which included [more than 240 improvements]({{ site.baseurl }}/blog/2016/08/30/drill-1.8-released/). Today we're happy to announce the availability of Drill 0.9, providing additional enhancements and bug fixes. In fact, this release includes [200 resolved JIRAs](https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12313820&version=12328813). Some of the noteworthy features in Drill 0.9 are:
+
+* **Authentication** ([DRILL-2674](https://issues.apache.org/jira/browse/DRILL-2674)). Drill now supports username/password authentication through the Java and C++ clients, as well as JDBC and ODBC. On the server-side, Drill leverages Linux PAM to securely validate the credentials. Users can choose to use an external user directory such as Active Directory or LDAP. To enable authentication, set the `security.user.auth` option in `drill-override.conf`.
+* **Impersonation** ([DRILL-2363](https://issues.apache.org/jira/browse/DRILL-2363)). Queries now execute and access resources using the identity of the user who submitted the query. Previously, all queries would run as the same user (eg, `drill`). With the new impersonation capability, the query will fail if the submitting user does not have permission to read the requested file(s) in the distributed file system. To enable impersonation, set the `drill.exec.impersonation` option in `drill-override.conf`.
+* **Ownership chaining**. Drill now allows views with different owners to be chained. This represents a very flexible access control solution. For example, an administrator with access to raw, sensitive data could create a view called `masked` which would expose only a subset of the data to other users. The administrator would enable users to read the `masked` view but not the raw data. Note that Drill provides an option `max_chained_user_hops` that specifies how many ownership changed are allowed in a chain, thereby providing administrators (or data stewards) more control over sharing of data.
+* **MongoDB authentication** ([DRILL-1502](https://issues.apache.org/jira/browse/DRILL-1502)). Drill can now connect to a MongoDB cluster that requires authentication.
+* **Extended JSON datatypes**. Our friends at MongoDB invented [extended JSON](http://docs.mongodb.org/manual/reference/mongodb-extended-json/) - a set of extensions to the JSON format for supporting additional data types. We decided to embrace extended JSON in Drill. For example, standard JSON doesn't have a time type, so a time could be represented as either a string or a number: `{"foo": "19:20:30.450Z"}` is just a string. With extended JSON, the `$time` qualifier can be used to specify that `foo` is a time `{"foo": {"$time": "19:20:30.450Z"}}`.
+ We now support a number of qualifiers including `$bin`, `$date`, `$time`, `$interval`, `$numberLong` and `$dateDay` (see [the example](https://github.com/apache/drill/blob/master/exec/java-exec/src/test/resources/vector/complex/extended.json)). We're in the process of adding some additional qualifiers to make sure that all of MongoDB's extended types are supported (this is particularly important when querying data in MongoDB).
+* **Avro support** ([DRILL-1512](https://issues.apache.org/jira/browse/DRILL-1512)). Drill can now read Avro files. This patch was contributed by Andrew Selden at Elastic.co (formerly known as Elasticsearch).
+* **Improved error messages** ([DRILL-2675](https://issues.apache.org/jira/browse/DRILL-2675) and more). It can be challenging for a complex distributed system like Drill to translate low-level internal conditions into actionable messages to the user. This release includes several enhancements that enable Drill to accomplish just that in a variety of cases.
+* **Parquet and Calcite enhancements** ([DRILL-1410](https://issues.apache.org/jira/browse/DRILL-1410) and [DRILL-1384](https://issues.apache.org/jira/browse/DRILL-1384)). Drill isn't a traditional query engine - it's the first analytical query engine with a JSON data model. This has required us to enhance Parquet (our columnar format) and Calcite (our SQL parser). These enhancements have now been contributed back to those projects, and Drill is using the latest versions which include these enhancements.
+* **New sys tables for memory and thread information** ([DRILL-2275](https://issues.apache.org/jira/browse/DRILL-2275)). Drill includes two new `sys` tables that provide real-time metrics about memory utilization and threads on each of the nodes in the cluster. You can run a simple `SELECT *` to see what information is available:
+
+ ```sql
+ SELECT * FROM sys.drillmemory;
+ SELECT * FROM sys.drillbitthreads;
+ ```
+
+* **Support for very wide tables** ([DRILL-2739](https://issues.apache.org/jira/browse/DRILL-2739)). Drill previously had some issues with tables that had more than 4095 colums. This limitation has been addressed.
+
+You can now [download Drill 0.9]({{ site.baseurl }}/download/). As always, you can check out the official [release notes]({{ site.baseurl }}/docs/release-notes/) for more details.
+
+We're gearing up for Drill's 1.0 release later this month. Stay tuned!

+### Milestone 1 Goals
+
+The first release of Apache Drill is designed as a technology preview for
+people to better understand the architecture and vision. It is a functional
+release tying to piece together the key components of a next generation MPP
+query engine. It is designed to allow milestone 2 (M2) to focus on
+architectural analysis and performance optimization.
+
+ * Provide a new optimistic DAG execution engine for data analysis
+ * Build a new columnar shredded in-memory format and execution model that minimizes data serialization/deserialization costs and operator complexity
+ * Provide a model for runtime generated functions and relational operators that minimizes complexity and maximizes performance
+ * Support queries against columnar on disk format (Parquet) and JSON
+ * Support the most common set of standard SQL read-only phrases using ANSI standards. Includes: SELECT, FROM, WHERE, HAVING, ORDER, GROUP BY, IN, DISTINCT, LEFT JOIN, RIGHT JOIN, INNER JOIN
+ * Support schema-on-read querying and execution
+ * Build a set of columnar operation primitives including Merge Join, Sort, Streaming Aggregate, Filter, Selection Vector removal.
+ * Support unlimited level of subqueries and correlated subqueries
+ * Provided an extensible query-language agnostic JSON-base logical data flow syntax.
+ * Support complex data type manipulation via logical plan operations
+
+### Known Issues
+
+SQL Parsing
+Because Apache Drill is built to support late-bound changing schemas while SQL
+is statically typed, there are couple of special requirements that are
+required writing SQL queries. These are limited to the current release and
+will be correct in a future milestone release.

+code: drill-1.11-released
+excerpt: Apache Drill 1.11's highlights are: Cryptography-related functions, spill to disk for the hash aggregate operator, Format plugin support for PCAP files, ability to change the HDFS block Size for Parquet files, ability to store query profiles in memory, configurable CTAS directory and file permissions option, support for network encryption, relative paths stored in the metadata file, and support for ANSI_QUOTES.
+authors: ["bbevens"]
+---
+
+Today, we're happy to announce the availability of Drill 1.11.0. You can download it [here](https://drill.apache.org/download/).
+
+The release provides the following bug fixes and improvements:
+
+## Cryptography-Related Functions (DRILL-5634)
+Drill provides the following cryptographic-related functions:
+
+- aes_encrypt()
+- aes_decrypt()
+- md5()
+- sha()
+- sha1()
+- sha2()
+
+## Spill to Disk for Hash Aggregate Operator (DRILL-5457)
+The Hash aggregate operator can spill data to disk in cases where the operation exceeds the set memory limit.
+
+## Format Plugin Support for PCAP Files (DRILL-5432)
+A “pcap” format plugin enables Drill to read PCAP files. You must add the “pcap” format to the dfs storage plugin configuration, as shown:
+
+ "pcap": {
+ "type": "pcap",
+ "extensions": [
+ "pcap"
+ ]
+ }
+
+## Change the HDFS Block Size for Parquet Files (DRILL-5379)
+The `store.parquet.writer.use_single_fs_block` option enables Drill to write a Parquet file as a single file system block without changing the file system default block size.
+
+## Store Query Profiles in Memory (DRILL-5481)
+The `drill.exec.profiles.store.inmemory` option enables Drill to store query profiles in memory instead of writing the query profiles to disk. The `drill.exec.profiles.store.capacity` option sets the maximum number of most recent profiles to retain in memory.
+
+## Configurable CTAS Directory and File Permissions Option (DRILL-5391)
+You can use the `exec.persistent_table.umask` configuration option, at the system or session level, to modify permissions on directories and files that result from running the CTAS command. By default, the option is set to 002, which sets the default directory permissions to 775 and default file permissions to -664.
+
+## Support for Network Encryption (DRILL-4335)
+Drill can use SASL to support network encryption between the Drill client and drillbits, and also between drillbits.
+
+## Metadata file Stores Relative Paths (DRILL-3867)
+Drill now stores the relative path in the metadata file (versus the absolute path), which enables you to move partitioned Parquet directories from one location in DFS to another without having to rebuild the Parquet metadata files; the metadata remains valid in the new location.
+
+## Support for ANSI_QUOTES (DRILL-3510)
+In addition to back ticks, the SQL parser in Drill can use double quotes as identifier quotes. Use the `planner.parser.quoting_identifiers` configuration option, at the system or session level, to set the type of identifier quotes that the SQL parser in Drill uses.
+
+You can find a complete list of JIRAs resolved in the 1.11.0 release [here](https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12313820&version=12339943).

-title: "Apache Drill 1.1.0 Release Notes"
-parent: "Release Notes"
----
-
-**Release date:** July 5, 2015
-
-It has been about 6 weeks since the release of Drill 1.0.0. Today we're happy to announce the availability of Drill 1.1.0, providing 119 additional enhancements and bug fixes.
-
-## Noteworthy New Features in Drill 1.1.0
-
-Drill now supports window functions, automatic partitioning, and Hive impersonation.
-
-### [Ranking Window Functions]({{site.baseurl}}/docs/ranking-window-functions/)
-
-* ROW_NUMBER
-* RANK
-* DENSE_RANK
-* PERCENT_RANK
-* CUME _DIST
-
-### [Aggregate Window Functions]({{site.baseurl}}/docs/aggregate-window-functions/)
-
-* COUNT
-* SUM
-* MIN
-* MAX
-* AVG
-
-### [Automatic Partitioning]({{site.baseurl}}/docs/partition-pruning/#automatic-partitioning) in CTAS (DRILL-3333)
-
-When a table is created with a partition by clause, the parquet writer will create separate files for the different partition values. The data will first be sorted by the partition keys, and the parquet writer will create a new file when it encounters a new value for the partition columns.
-
-When queries are issued against data that was created this way, partition pruning will work if the filter contains a partition column. Unlike directory-based partitioning, no view is required, nor is it necessary to reference the dir* column names.
-
-### [Hive impersonation]({{site.baseurl}}/docs/configuring-user-impersonation-with-hive-authorization) support (DRILL-3203)
-
-When impersonation is enabled, Drill now supports impersonating the user who issued the query when accessing Hive metadata/data (instead of accessing Hive as the user that started the drillbit).
-

+* Improvements in the Drill JDBC driver including inclusion of
+[Javadocs]({{site.baseurl}}/api/1.2/jdbc/) and better application dependency compatibility
+* Enhancements to Avro file formats
+ * [Support for complex data types](https://issues.apache.org/jira/browse/DRILL-3565), such as UNION and MAP
+ * [Optimized Avro file processing](https://issues.apache.org/jira/browse/DRILL-3720) (block-wise)
+* Partition pruning improvements
+* A number of new [SQL window functions]({{site.baseurl}}/docs/sql-window-functions)
+ * NTILE
+ * LAG and LEAD
+ * FIRST_VALUE and LAST_VALUE
+* [HTTPS support]({{site.baseurl}}/docs/configuring-web-console-and-rest-api-security/) for Web Console operations

+## Important Unresolved Issues
+
+* The Drill error message about JSON syntax that appears when Drill cannot find the JDBC driver during configuration of the JDBC storage plugin is misleading. To configure the JDBC plugin, you must put the JDBC driver in the `<drill_installation_directory>/jars/3rdparty` directory. [DRILL-3985](https://issues.apache.org/jira/browse/DRILL-3958)
+* The MySQL TEXT type is not supported. The popular classicmodels database uses the TEXT type, and therefore cannot be used as is until this issue is resolved. [DRILL-3956](https://issues.apache.org/jira/browse/DRILL-3956)

----
-
-**Release date:** December 14, 2015
-
-Today, we're happy to announce the availability of Drill 1.4.0, providing the following bug fixes and improvements.
-
-Drill 1.4 fixes an error that occurred when querying a Hive table using the HBaseStorageHandler ([DRILL-3739](https://issues.apache.org/jira/browse/DRILL-3739)). To successfully query a Hive table using the HBaseStorageHandler, you need to configure the Hive storage plugin as described in the [Hive storage plugin documentation]({{site.baseurl}}/docs/hive-storage-plugin/#connect-drill-to-the-hive-remote-metastore).

+
+**Release date:** December 14, 2015
+
+Today, we're happy to announce the availability of Drill 1.4.0, providing the following bug fixes and improvements.
+
+Drill 1.4 fixes an error that occurred when querying a Hive table using the HBaseStorageHandler ([DRILL-3739](https://issues.apache.org/jira/browse/DRILL-3739)). To successfully query a Hive table using the HBaseStorageHandler, you need to configure the Hive storage plugin as described in the [Hive storage plugin documentation]({{site.baseurl}}/docs/hive-storage-plugin/#connect-drill-to-the-hive-remote-metastore).

-
-## Important Unresolved Issues
-
-* The Drill error message about JSON syntax that appears when Drill cannot find the JDBC driver during configuration of the JDBC storage plugin is misleading. To configure the JDBC plugin, you must put the JDBC driver in the `<drill_installation_directory>/jars/3rdparty` directory. [DRILL-3985](https://issues.apache.org/jira/browse/DRILL-3958)
-* The MySQL TEXT type is not supported. The popular classicmodels database uses the TEXT type, and therefore cannot be used as is until this issue is resolved. [DRILL-3956](https://issues.apache.org/jira/browse/DRILL-3956)

-title: "Apache Drill 1.8.0 Release Notes"
-parent: "Release Notes"
----
-
-**Release date:** August 30, 2016
-
-Today, we're happy to announce the availability of Drill 1.8.0. You can download it [here](https://drill.apache.org/download/).
-
-## New Features
-This release of Drill provides the following new features:
-
-- Metadata cache pruning
-- IF EXISTS parameter with the DROP TABLE and DROP VIEW commands
-- DESCRIBE SCHEMA command
-- Multi-byte delimiter support
-- New parameters for filter selectivity estimates
-
-## Configuration and Launch Script Changes
-This release of Drill also includes the following changes to the configuration and launch scripts:
-
-- The `$DRILL_HOME/conf/drill-env.sh` file has been simplified. Default Drill settings have moved out of this file and now reside in `$DRILL_HOME/bin/drill-config.sh`. The `drill-env.sh` file now ships with descriptions of the options that you can set. You can override many settings by creating an entry in `$DRILL_HOME/conf/drill-env.sh`. ([DRILL-4581](https://issues.apache.org/jira/browse/DRILL-4581))
-- Due to issues at high concurrency, the native Linux epoll transport is now disabled by default. ([DRILL-4623](https://issues.apache.org/jira/browse/DRILL-4623))
-
-Changes to the Drill launch scripts provide a new option that simplifies the Drill upgrade for Drill 1.8 and later. The new scripts support a “site directory” that holds site-specific files separate from the Drill product directory. The site directory is a simple extension of the config directory in previous Drill releases. You can add a “jars” subdirectory to the config directory for your custom jars instead of storing them in $DRILL_HOME. You can even add native libraries in the new “lib” directory and Drill automatically loads them.
-
-Example:
-
- /my/conf/dir
- |- drill-override.conf
- |- drill-env.sh
- |- jars
- |- myudf.jar
- |- lib
- |- mysecurity.so
-
-To use the site directory:
-
- drillbit.sh —site /my/conf/dir start
-
-Note that `--config` still works as well.
-
-You can set an environment variable for the directory:
-
- export DRILL_CONF_DIR=/my/conf/dir
- drillbit.sh start
-
-The site directory works with `drillbit.sh` and the various Drill client scripts.
-
-To upgrade Drill using the new site directory, just delete the old Drill product directory and expand the Drill archive to create a new one. There is no need to back up and merge files each time you upgrade because the site files are not affected by an upgrade. Using the site directory, you can have different site directories for different Drill sessions: one for development, another for test, and so on. You can use the site directory to run multiple Drill clusters from as single Drill installation by creating a site directory for each Drill cluster and then configuring Drill.
-
-The following sections list additional bug fixes and improvements:

+title: "Apache Drill 1.8.0 Release Notes"
+parent: "Release Notes"
+---
+
+**Release date:** August 30, 2016
+
+Today, we're happy to announce the availability of Drill 1.8.0. You can download it [here](https://drill.apache.org/download/).
+
+## New Features
+This release of Drill provides the following new features:
+
+- Metadata cache pruning
+- IF EXISTS parameter with the DROP TABLE and DROP VIEW commands
+- DESCRIBE SCHEMA command
+- Multi-byte delimiter support
+- New parameters for filter selectivity estimates
+
+## Configuration and Launch Script Changes
+This release of Drill also includes the following changes to the configuration and launch scripts:
+
+- The `$DRILL_HOME/conf/drill-env.sh` file has been simplified. Default Drill settings have moved out of this file and now reside in `$DRILL_HOME/bin/drill-config.sh`. The `drill-env.sh` file now ships with descriptions of the options that you can set. You can override many settings by creating an entry in `$DRILL_HOME/conf/drill-env.sh`. ([DRILL-4581](https://issues.apache.org/jira/browse/DRILL-4581))
+- Due to issues at high concurrency, the native Linux epoll transport is now disabled by default. ([DRILL-4623](https://issues.apache.org/jira/browse/DRILL-4623))
+
+Changes to the Drill launch scripts provide a new option that simplifies the Drill upgrade for Drill 1.8 and later. The new scripts support a “site directory” that holds site-specific files separate from the Drill product directory. The site directory is a simple extension of the config directory in previous Drill releases. You can add a “jars” subdirectory to the config directory for your custom jars instead of storing them in $DRILL_HOME. You can even add native libraries in the new “lib” directory and Drill automatically loads them.
+
+Example:
+
+ /my/conf/dir
+ |- drill-override.conf
+ |- drill-env.sh
+ |- jars
+ |- myudf.jar
+ |- lib
+ |- mysecurity.so
+
+To use the site directory:
+
+ drillbit.sh —site /my/conf/dir start
+
+Note that `--config` still works as well.
+
+You can set an environment variable for the directory:
+
+ export DRILL_CONF_DIR=/my/conf/dir
+ drillbit.sh start
+
+The site directory works with `drillbit.sh` and the various Drill client scripts.
+
+To upgrade Drill using the new site directory, just delete the old Drill product directory and expand the Drill archive to create a new one. There is no need to back up and merge files each time you upgrade because the site files are not affected by an upgrade. Using the site directory, you can have different site directories for different Drill sessions: one for development, another for test, and so on. You can use the site directory to run multiple Drill clusters from as single Drill installation by creating a site directory for each Drill cluster and then configuring Drill.
+
+The following sections list additional bug fixes and improvements:

- 1. Download the latest version of Apache Drill [here](http://apache.mirrors.hoobly.com/drill/drill-1.10.0/apache-drill-1.10.0.tar.gz) or from the [Apache Drill mirror site](http://www.apache.org/dyn/closer.cgi/drill/drill-1.10.0/apache-drill-1.10.0.tar.gz) with the command appropriate for your system:
- * `wget http://apache.mirrors.hoobly.com/drill/drill-1.10.0/apache-drill-1.10.0.tar.gz`
- * `curl -o apache-drill-1.10.0.tar.gz http://apache.mirrors.hoobly.com/drill/drill-1.10.0/apache-drill-1.10.0.tar.gz`

First, check that you [meet the prerequisites]({{site.baseurl}}/docs/embedded-mode-prerequisites), including setting the JAVA_HOME environment variable, and then install Drill. Currently, Drill supports 64-bit Windows only. Complete the following steps to install Drill:
-1. Download the latest version of Apache Drill [here](http://apache.mirrors.hoobly.com/drill/drill-1.10.0/apache-drill-1.10.0.tar.gz).
+1. Download the latest version of Apache Drill [here](http://apache.mirrors.hoobly.com/drill/drill-1.11.0/apache-drill-1.11.0.tar.gz).
2. Move the downloaded file to the directory where you want to install Drill.
3. Unzip the GZ file using a third-party tool. If the tool you use does not unzip the underlying TAR file as well as the GZ file, perform a second unzip to extract the Drill software. The extraction process creates the installation directory containing the Drill software.

-**Release date:** May 19, 2015
-
-Today we're happy to announce the availability of Drill 1.0.0, providing additional enhancements and bug fixes. This release includes the following new features, enhancements, unresolved issues, and bug fixes:
-
-<h2> Sub-task
-</h2>
-<ul>
-<li>[<a href='https://issues.apache.org/jira/browse/DRILL-2150'>DRILL-2150</a>] - Create an abstraction for repeated value vectors.
-</li>
-<li>[<a href='https://issues.apache.org/jira/browse/DRILL-2358'>DRILL-2358</a>] - Ensure DrillScanRel differentiates skip-all, scan-all & scan-some in a backward compatible fashion
-</li>
-<li>[<a href='https://issues.apache.org/jira/browse/DRILL-2893'>DRILL-2893</a>] - ScanBatch throws a NullPointerException instead of returning OUT_OF_MEMORY
-</li>
-<li>[<a href='https://issues.apache.org/jira/browse/DRILL-2895'>DRILL-2895</a>] - AbstractRecordBatch.buildSchema() should properly handle OUT_OF_MEMORY outcome
-</li>
-<li>[<a href='https://issues.apache.org/jira/browse/DRILL-2902'>DRILL-2902</a>] - Add support for context UDFs: user (and its synonyms session_user, system_user) and current_schema
-</li>
-<li>[<a href='https://issues.apache.org/jira/browse/DRILL-2905'>DRILL-2905</a>] - RootExec implementations should properly handle IterOutcome.OUT_OF_MEMORY
-</li>
-<li>[<a href='https://issues.apache.org/jira/browse/DRILL-2920'>DRILL-2920</a>] - properly handle OutOfMemoryException
-</li>
-<li>[<a href='https://issues.apache.org/jira/browse/DRILL-2947'>DRILL-2947</a>] - AllocationHelper.allocateNew() doesn't have a consistent behavior when it can't allocate
-</li>
-</ul>
-
-<h2> Unresolved Issues
-</h2>
-<ul>
- <li>[<a href='https://issues.apache.org/jira/browse/DRILL-1868'>DRILL-1868</a>] Aliases are not allowed in WHERE, HAVING and GROUP BY clauses. Drill should return an error when such aliases are encountered, but instead Drill returns an incorrect result.
- </li>
- <li>[<a href='https://issues.apache.org/jira/browse/DRILL-2015'>DRILL-2015</a>] Casting a numeric value that does not fit the data type of the value and causes overflow returns an incorrect result.
- </li>
- <li>[<a href='https://issues.apache.org/jira/browse/DRILL-2355'>DRILL-2355</a>] Drill output from the TRUNC function in some cases includes an extra .0 in the result. Drill binds TRUNC functions having two input parameters to the function holder. The output type of TRUNC functions is FLOAT8 when the input is FLOAT8, resulting in the extra .0.
- </li>

+title: "Apache Drill 1.1.0 Release Notes"
+parent: "Release Notes"
+---
+
+**Release date:** July 5, 2015
+
+It has been about 6 weeks since the release of Drill 1.0.0. Today we're happy to announce the availability of Drill 1.1.0, providing 119 additional enhancements and bug fixes.
+
+## Noteworthy New Features in Drill 1.1.0
+
+Drill now supports window functions, automatic partitioning, and Hive impersonation.
+
+### [Ranking Window Functions]({{site.baseurl}}/docs/ranking-window-functions/)
+
+* ROW_NUMBER
+* RANK
+* DENSE_RANK
+* PERCENT_RANK
+* CUME _DIST
+
+### [Aggregate Window Functions]({{site.baseurl}}/docs/aggregate-window-functions/)
+
+* COUNT
+* SUM
+* MIN
+* MAX
+* AVG
+
+### [Automatic Partitioning]({{site.baseurl}}/docs/partition-pruning/#automatic-partitioning) in CTAS (DRILL-3333)
+
+When a table is created with a partition by clause, the parquet writer will create separate files for the different partition values. The data will first be sorted by the partition keys, and the parquet writer will create a new file when it encounters a new value for the partition columns.
+
+When queries are issued against data that was created this way, partition pruning will work if the filter contains a partition column. Unlike directory-based partitioning, no view is required, nor is it necessary to reference the dir* column names.
+
+### [Hive impersonation]({{site.baseurl}}/docs/configuring-user-impersonation-with-hive-authorization) support (DRILL-3203)
+
+When impersonation is enabled, Drill now supports impersonating the user who issued the query when accessing Hive metadata/data (instead of accessing Hive as the user that started the drillbit).
+

-title: "Apache Drill 0.9.0 Release Notes"
-parent: "Release Notes"
----
-It has been about a month since the release of Drill 0.8, which included [more than 240 improvements]({{ site.baseurl }}/blog/2016/08/30/drill-1.8-released/). Today we're happy to announce the availability of Drill 0.9, providing additional enhancements and bug fixes. In fact, this release includes [200 resolved JIRAs](https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12313820&version=12328813). Some of the noteworthy features in Drill 0.9 are:
-
-* **Authentication** ([DRILL-2674](https://issues.apache.org/jira/browse/DRILL-2674)). Drill now supports username/password authentication through the Java and C++ clients, as well as JDBC and ODBC. On the server-side, Drill leverages Linux PAM to securely validate the credentials. Users can choose to use an external user directory such as Active Directory or LDAP. To enable authentication, set the `security.user.auth` option in `drill-override.conf`.
-* **Impersonation** ([DRILL-2363](https://issues.apache.org/jira/browse/DRILL-2363)). Queries now execute and access resources using the identity of the user who submitted the query. Previously, all queries would run as the same user (eg, `drill`). With the new impersonation capability, the query will fail if the submitting user does not have permission to read the requested file(s) in the distributed file system. To enable impersonation, set the `drill.exec.impersonation` option in `drill-override.conf`.
-* **Ownership chaining**. Drill now allows views with different owners to be chained. This represents a very flexible access control solution. For example, an administrator with access to raw, sensitive data could create a view called `masked` which would expose only a subset of the data to other users. The administrator would enable users to read the `masked` view but not the raw data. Note that Drill provides an option `max_chained_user_hops` that specifies how many ownership changed are allowed in a chain, thereby providing administrators (or data stewards) more control over sharing of data.
-* **MongoDB authentication** ([DRILL-1502](https://issues.apache.org/jira/browse/DRILL-1502)). Drill can now connect to a MongoDB cluster that requires authentication.
-* **Extended JSON datatypes**. Our friends at MongoDB invented [extended JSON](http://docs.mongodb.org/manual/reference/mongodb-extended-json/) - a set of extensions to the JSON format for supporting additional data types. We decided to embrace extended JSON in Drill. For example, standard JSON doesn't have a time type, so a time could be represented as either a string or a number: `{"foo": "19:20:30.450Z"}` is just a string. With extended JSON, the `$time` qualifier can be used to specify that `foo` is a time `{"foo": {"$time": "19:20:30.450Z"}}`.
- We now support a number of qualifiers including `$bin`, `$date`, `$time`, `$interval`, `$numberLong` and `$dateDay` (see [the example](https://github.com/apache/drill/blob/master/exec/java-exec/src/test/resources/vector/complex/extended.json)). We're in the process of adding some additional qualifiers to make sure that all of MongoDB's extended types are supported (this is particularly important when querying data in MongoDB).
-* **Avro support** ([DRILL-1512](https://issues.apache.org/jira/browse/DRILL-1512)). Drill can now read Avro files. This patch was contributed by Andrew Selden at Elastic.co (formerly known as Elasticsearch).
-* **Improved error messages** ([DRILL-2675](https://issues.apache.org/jira/browse/DRILL-2675) and more). It can be challenging for a complex distributed system like Drill to translate low-level internal conditions into actionable messages to the user. This release includes several enhancements that enable Drill to accomplish just that in a variety of cases.
-* **Parquet and Calcite enhancements** ([DRILL-1410](https://issues.apache.org/jira/browse/DRILL-1410) and [DRILL-1384](https://issues.apache.org/jira/browse/DRILL-1384)). Drill isn't a traditional query engine - it's the first analytical query engine with a JSON data model. This has required us to enhance Parquet (our columnar format) and Calcite (our SQL parser). These enhancements have now been contributed back to those projects, and Drill is using the latest versions which include these enhancements.
-* **New sys tables for memory and thread information** ([DRILL-2275](https://issues.apache.org/jira/browse/DRILL-2275)). Drill includes two new `sys` tables that provide real-time metrics about memory utilization and threads on each of the nodes in the cluster. You can run a simple `SELECT *` to see what information is available:
-
- ```sql
- SELECT * FROM sys.drillmemory;
- SELECT * FROM sys.drillbitthreads;
- ```
-
-* **Support for very wide tables** ([DRILL-2739](https://issues.apache.org/jira/browse/DRILL-2739)). Drill previously had some issues with tables that had more than 4095 colums. This limitation has been addressed.
