* [SPARK-15095][SQL] drop binary mode in ThriftServerDavies Liu2016-05-033-47/+14
| | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This PR drop the support for binary mode in ThriftServer, only HTTP mode is supported now, to reduce the maintain burden. The code to support binary mode is still kept, just in case if we want it in future. ## How was this patch tested? Updated tests to use HTTP mode. Author: Davies Liu <davies@databricks.com> Closes #12876 from davies/hide_binary.

After passing Jenkins building, run `dev/lint-java` manually. ```bash $ dev/lint-java Checkstyle checks passed. ``` Author: Dongjoon Hyun <dongjoon@apache.org> Closes #12831 from dongjoon-hyun/SPARK-15053.
* [SPARK-15004][SQL] Remove zookeeper service discovery code in thrift-serverReynold Xin2016-04-295-506/+6
| | | | | | | | | | | | ## What changes were proposed in this pull request? We recently inlined Hive's thrift server code in SPARK-15004. This patch removes the code related to zookeeper service discovery, Tez, and Hive on Spark, since they are irrelevant. ## How was this patch tested? N/A - removing dead code Author: Reynold Xin <rxin@databricks.com> Closes #12780 from rxin/SPARK-15004.

* [SPARK-14721][SQL] Remove HiveContext (part 2)Andrew Or2016-04-258-48/+54
| | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This removes the class `HiveContext` itself along with all code usages associated with it. The bulk of the work was already done in #12485. This is mainly just code cleanup and actually removing the class. Note: A couple of things will break after this patch. These will be fixed separately. - the python HiveContext - all the documentation / comments referencing HiveContext - there will be no more HiveContext in the REPL (fixed by #12589) ## How was this patch tested? No change in functionality. Author: Andrew Or <andrew@databricks.com> Closes #12585 from andrewor14/delete-hive-context.

| | | | | | | | | | | | ## What changes were proposed in this pull request? It is unnecessary as DataType.catalogString largely replaces the need for this class. ## How was this patch tested? Mostly removing dead code and should be covered by existing tests. Author: Reynold Xin <rxin@databricks.com> Closes #12644 from rxin/SPARK-14877.
* [SPARK-14869][SQL] Don't mask exceptions in ResolveRelationsReynold Xin2016-04-231-1/+1
| | | | | | | | | | | | ## What changes were proposed in this pull request? In order to support running SQL directly on files, we added some code in ResolveRelations to catch the exception thrown by catalog.lookupRelation and ignore it. This unfortunately masks all the exceptions. This patch changes the logic to simply test the table's existence. ## How was this patch tested? I manually hacked some bugs into Spark and made sure the exceptions were being propagated up. Author: Reynold Xin <rxin@databricks.com> Closes #12634 from rxin/SPARK-14869.
* [SPARK-14871][SQL] Disable StatsReportListener to declutter outputReynold Xin2016-04-231-2/+0
| | | | | | | | | | | | ## What changes were proposed in this pull request? Spark SQL inherited from Shark to use the StatsReportListener. Unfortunately this clutters the spark-sql CLI output and makes it very difficult to read the actual query results. ## How was this patch tested? Built and tested in spark-sql CLI. Author: Reynold Xin <rxin@databricks.com> Closes #12635 from rxin/SPARK-14871.
* [SPARK-14855][SQL] Add "Exec" suffix to physical operatorsReynold Xin2016-04-221-2/+2
| | | | | | | | | | | | ## What changes were proposed in this pull request? This patch adds "Exec" suffix to all physical operators. Before this patch, Spark's physical operators and logical operators are named the same (e.g. Project could be logical.Project or execution.Project), which caused small issues in code review and bigger issues in code refactoring. ## How was this patch tested? N/A Author: Reynold Xin <rxin@databricks.com> Closes #12617 from rxin/exec-node.

| | | | | | | | | | | | | | ## What changes were proposed in this pull request? Add the native support for LOAD DATA DDL command that loads data into Hive table/partition. ## How was this patch tested? `HiveDDLCommandSuite` and `HiveQuerySuite`. Besides, few Hive tests (`WindowQuerySuite`, `HiveTableScanSuite` and `HiveSerDeSuite`) also use `LOAD DATA` command.

Move Hive-specific methods from HiveContext to HiveSessionState, which help the work of removing HiveContext. 2. Create a SparkSession Class, which will later be the entry point of Spark SQL users. ## How was this patch tested?

* [SPARK-14676] Wrap and re-throw Await.result exceptions in order to capture ↵Josh Rosen2016-04-192-10/+11
| | | | | | | | | | | | | | | | full stacktrace When `Await.result` throws an exception which originated from a different thread, the resulting stacktrace doesn't include the path leading to the `Await.result` call itself, making it difficult to identify the impact of these exceptions. For example, I've seen cases where broadcast cleaning errors propagate to the main thread and crash it but the resulting stacktrace doesn't include any of the main thread's code, making it difficult to pinpoint which exception crashed that thread. This patch addresses this issue by explicitly catching, wrapping, and re-throwing exceptions that are thrown by `Await.result`. I tested this manually using https://github.com/JoshRosen/spark/commit/16b31c825197ee31a50214c6ba3c1df08148f403, a patch which reproduces an issue where an RPC exception which occurs while unpersisting RDDs manages to crash the main thread without any useful stacktrace, and verified that informative, full stacktraces were generated after applying the fix in this PR. /cc rxin nongli yhuai anabranch Author: Josh Rosen <joshrosen@databricks.com> Closes #12433 from JoshRosen/wrap-and-rethrow-await-exceptions.
* [SPARK-14674][SQL] Move HiveContext.hiveconf to HiveSessionStateAndrew Or2016-04-182-5/+4
| | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This is just cleanup. This allows us to remove HiveContext later without inflating the diff too much. This PR fixes the conflicts of https://github.com/apache/spark/pull/12431. It also removes the `def hiveConf` from `HiveSqlParser`. So, we will pass the HiveConf associated with a session explicitly instead of relying on Hive's `SessionState` to pass `HiveConf`. ## How was this patch tested? Existing tests. Closes #12431 Author: Andrew Or <andrew@databricks.com> Author: Yin Huai <yhuai@databricks.com> Closes #12449 from yhuai/hiveconf.
* [SPARK-14388][SQL] Implement CREATE TABLEAndrew Or2016-04-131-4/+4
| | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This patch implements the `CREATE TABLE` command using the `SessionCatalog`. Previously we handled only `CTAS` and `CREATE TABLE ... USING`. This requires us to refactor `CatalogTable` to accept various fields (e.g. bucket and skew columns) and pass them to Hive. WIP: Note that I haven't verified whether this actually works yet! But I believe it does. ## How was this patch tested? Tests will come in a future commit. Author: Andrew Or <andrew@databricks.com> Author: Yin Huai <yhuai@databricks.com> Closes #12271 from andrewor14/create-table-ddl.

It removes the function `isViewSupported` from `SessionCatalog`. After the removal, we still can capture the user errors if users try to drop a table using `DROP VIEW`. #### How was this patch tested?

* [SPARK-14362][SPARK-14406][SQL] DDL Native Support: Drop View and Drop Tablegatorsmile2016-04-091-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | #### What changes were proposed in this pull request? This PR is to provide a native support for DDL `DROP VIEW` and `DROP TABLE`. The PR includes native parsing and native analysis. Based on the HIVE DDL document for [DROP_VIEW_WEB_LINK](https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL- DropView ), `DROP VIEW` is defined as, **Syntax:** ```SQL DROP VIEW [IF EXISTS] [db_name.]view_name; ``` - to remove metadata for the specified view. - illegal to use DROP TABLE on a view. - illegal to use DROP VIEW on a table. - this command only works in `HiveContext`. In `SQLContext`, we will get an exception. This PR also handles `DROP TABLE`. **Syntax:** ```SQL DROP TABLE [IF EXISTS] table_name [PURGE]; ``` - Previously, the `DROP TABLE` command only can drop Hive tables in `HiveContext`. Now, after this PR, this command also can drop temporary table, external table, external data source table in `SQLContext`. - In `HiveContext`, we will not issue an exception if the to-be-dropped table does not exist and users did not specify `IF EXISTS`. Instead, we just log an error message. If `IF EXISTS` is specified, we will not issue any error message/exception. - In `SQLContext`, we will issue an exception if the to-be-dropped table does not exist, unless `IF EXISTS` is specified. - Data will not be deleted if the tables are `external`, unless table type is `managed_table`. #### How was this patch tested? For verifying command parsing, added test cases in `spark/sql/hive/HiveDDLCommandSuite.scala` For verifying command analysis, added test cases in `spark/sql/hive/execution/HiveDDLSuite.scala` Author: gatorsmile <gatorsmile@gmail.com> Author: xiaoli <lixiao1983@gmail.com> Author: Xiao Li <xiaoli@Xiaos-MacBook-Pro.local> Closes #12146 from gatorsmile/dropView.
* [SPARK-14123][SPARK-14384][SQL] Handle CreateFunction/DropFunctionYin Huai2016-04-051-43/+51
| | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This PR implements CreateFunction and DropFunction commands. Besides implementing these two commands, we also change how to manage functions. Here are the main changes. * `FunctionRegistry` will be a container to store all functions builders and it will not actively load any functions. Because of this change, we do not need to maintain a separate registry for HiveContext. So, `HiveFunctionRegistry` is deleted. * SessionCatalog takes care the job of loading a function if this function is not in the `FunctionRegistry` but its metadata is stored in the external catalog. For this case, SessionCatalog will (1) load the metadata from the external catalog, (2) load all needed resources (i.e. jars and files), (3) create a function builder based on the function definition, (4) register the function builder in the `FunctionRegistry`. * A `UnresolvedGenerator` is created. So, the parser will not need to call `FunctionRegistry` directly during parsing, which is not a good time to create a Hive UDTF. In the analysis phase, we will resolve `UnresolvedGenerator`. This PR is based on viirya's https://github.com/apache/spark/pull/12036/ ## How was this patch tested? Existing tests and new tests. ## TODOs [x] Self-review [x] Cleanup [x] More tests for create/drop functions (we need to more tests for permanent functions). [ ] File JIRAs for all TODOs [x] Standardize the error message when a function does not exist.

* [SPARK-13579][BUILD] Stop building the main Spark assembly.Marcelo Vanzin2016-04-041-0/+4
| | | | | | | | | | | | | | | | | | | | This change modifies the "assembly/" module to just copy needed dependencies to its build directory, and modifies the packaging script to pick those up (and remove duplicate jars packages in the examples module). I also made some minor adjustments to dependencies to remove some test jars from the final packaging, and remove jars that conflict with each other when packaged separately (e.g. servlet api). Also note that this change restores guava in applications' classpaths, even though it's still shaded inside Spark. This is now needed for the Hadoop libraries that are packaged with Spark, which now are not processed by the shade plugin.

* [SPARK-14334] [SQL] add toLocalIterator for Dataset/DataFrameDavies Liu2016-04-041-1/+1
| | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? RDD.toLocalIterator() could be used to fetch one partition at a time to reduce the memory usage. Right now, for Dataset/Dataframe we have to use df.rdd.toLocalIterator, which is super slow also requires lots of memory (because of the Java serializer or even Kyro serializer). This PR introduce an optimized toLocalIterator for Dataset/DataFrame, which is much faster and requires much less memory. For a partition with 5 millions rows, `df.rdd.toIterator` took about 100 seconds, but df.toIterator took less than 7 seconds. For 10 millions row, rdd.toIterator will crash (not enough memory) with 4G heap, but df.toLocalIterator could finished in 12 seconds. The JDBC server has been updated to use DataFrame.toIterator. ## How was this patch tested? Existing tests. Author: Davies Liu <davies@databricks.com> Closes #12114 from davies/local_iterator.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SHOW TABLE to use table identifier pattern ## What changes were proposed in this pull request? This PR addresses the following 1. Supports native execution of SHOW DATABASES command 2. Fixes SHOW TABLES to apply the identifier_with_wildcards pattern if supplied. SHOW TABLE syntax ``` SHOW TABLES [IN database_name] ['identifier_with_wildcards']; ``` SHOW DATABASES syntax ``` SHOW (DATABASES|SCHEMAS) [LIKE 'identifier_with_wildcards']; ``` ## How was this patch tested? Tests added in SQLQuerySuite (both hive and sql contexts) and DDLCommandSuite Note: Since the table name pattern was not working , tests are added in both SQLQuerySuite to verify the application of the table pattern.

| | | | | | | | | | | | | | | | | | | | | | #### What changes were proposed in this pull request? This PR is to implement the following four Database-related DDL commands: - `CREATE DATABASE|SCHEMA [IF NOT EXISTS] database_name` - `DROP DATABASE [IF EXISTS] database_name [RESTRICT|CASCADE]` - `DESCRIBE DATABASE [EXTENDED] db_name` - `ALTER (DATABASE|SCHEMA) database_name SET DBPROPERTIES (property_name=property_value, ...)` Another PR will be submitted to handle the unsupported commands.

| | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? `SessionCatalog`, introduced in #11750, is a catalog that keeps track of temporary functions and tables, and delegates metastore operations to `ExternalCatalog`. This functionality overlaps a lot with the existing `analysis.Catalog`. As of this commit, `SessionCatalog` and `ExternalCatalog` will no longer be dead code. There are still things that need to be done after this patch, namely: - SPARK-14013: Properly implement temporary functions in `SessionCatalog` - SPARK-13879: Decide which DDL/DML commands to support natively in Spark - SPARK-?????: Implement the ones we do want to support through `SessionCatalog`. - SPARK-?????: Merge SQL/HiveContext ## How was this patch tested? This is largely a refactoring task so there are no new tests introduced. The particularly relevant tests are `SessionCatalogSuite` and `ExternalCatalogSuite`.

| | | | | | | | | | | | The ```SparkSqlLexer``` currently swallows characters which have not been defined in the grammar. This causes problems with SQL commands, such as: ```add jar file:///tmp/ab/TestUDTF.jar```. In this example the `````` is swallowed. This PR adds an extra Lexer rule to handle such input, and makes a tiny modification to the ```ASTNode```. cc davies liancheng Author: Herman van Hovell <hvanhovell@questtec.nl> Closes #11052 from hvanhovell/SPARK-13157.

* [SPARK-6363][BUILD] Make Scala 2.11 the default Scala versionJosh Rosen2016-01-301-2/+2
| | | | | | | | | | | | This patch changes Spark's build to make Scala 2.11 the default Scala version. To be clear, this does not mean that Spark will stop supporting Scala 2.10: users will still be able to compile Spark for Scala 2.10 by following the instructions on the "Building Spark" page; however, it does mean that Scala 2.11 will be the default Scala version used by our CI builds (including pull request builds). The Scala 2.11 compiler is faster than 2.10, so I think we'll be able to look forward to a slight speedup in our CI builds (it looks like it's about 2X faster for the Maven compile-only builds, for instance). After this patch is merged, I'll update Jenkins to add new compile-only jobs to ensure that Scala 2.10 compilation doesn't break. Author: Josh Rosen <joshrosen@databricks.com> Closes #10608 from JoshRosen/SPARK-6363.
