* [MINOR] Follow-up to #12625Andrew Or2016-04-262-2/+2
| | | | | | | | | | ## What changes were proposed in this pull request? That patch mistakenly widened the visibility from `private[x]` to `protected[x]`. This patch reverts those changes. Author: Andrew Or <andrew@databricks.com> Closes #12686 from andrewor14/visibility.
* [SPARK-14912][SQL] Propagate data source options to Hadoop configurationReynold Xin2016-04-2611-52/+94
| | | | | | | | | | | | ## What changes were proposed in this pull request? We currently have no way for users to propagate options to the underlying library that rely in Hadoop configurations to work. For example, there are various options in parquet-mr that users might want to set, but the data source API does not expose a per-job way to set it. This patch propagates the user-specified options also into Hadoop Configuration. ## How was this patch tested? Used a mock data source implementation to test both the read path and the write path. Author: Reynold Xin <rxin@databricks.com> Closes #12688 from rxin/SPARK-14912.
* [SPARK-14910][SQL] Native DDL Command Support for Describe Function in ↵gatorsmile2016-04-264-3/+79
| | | | | | | | | | | | | | | | | | | | | | | | Non-identifier Format #### What changes were proposed in this pull request? The existing `Describe Function` only support the function name in `identifier`. This is different from what Hive behaves. That is why many test cases `udf_abc` in `HiveCompatibilitySuite` are not using our native DDL support. For example, - udf_not.q - udf_bitwise_not.q This PR is to resolve the issues. Now, we can support the command of `Describe Function` whose function names are in the following format: - `qualifiedName` (e.g., `db.func1`) - `STRING` (e.g., `'func1'`) - `comparisonOperator` (e.g,. `<`) - `arithmeticOperator` (e.g., `+`) - `predicateOperator` (e.g., `or`) Note, before this PR, we only have a native command support when the function name is in the format of `qualifiedName`. #### How was this patch tested? Added test cases in `DDLSuite.scala`. Also manually verified all the related test cases in `HiveCompatibilitySuite` passed. Author: gatorsmile <gatorsmile@gmail.com> Closes #12679 from gatorsmile/descFunction.

* [SPARK-14861][SQL] Replace internal usages of SQLContext with SparkSessionAndrew Or2016-04-2586-664/+719
| | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? In Spark 2.0, `SparkSession` is the new thing. Internally we should stop using `SQLContext` everywhere since that's supposed to be not the main user-facing API anymore. In this patch I took care to not break any public APIs. The one place that's suspect is `o.a.s.ml.source.libsvm.DefaultSource`, but according to mengxr it's not supposed to be public so it's OK to change the underlying `FileFormat` trait. **Reviewers**: This is a big patch that may be difficult to review but the changes are actually really straightforward. If you prefer I can break it up into a few smaller patches, but it will delay the progress of this issue a little. ## How was this patch tested? No change in functionality intended. Author: Andrew Or <andrew@databricks.com> Closes #12625 from andrewor14/spark-session-refactor.

| | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This is for users who can't upgrade and need to continue to use HiveContext. ## How was this patch tested? Added some basic tests for sanity check. This is based on #12672 and closes #12672. Author: Andrew Or <andrew@databricks.com> Author: Reynold Xin <rxin@databricks.com> Closes #12682 from rxin/add-back-hive-context.

* [SPARK-14902][SQL] Expose RuntimeConfig in SparkSessionAndrew Or2016-04-2538-81/+131
| | | | | | | | | | | | | | ## What changes were proposed in this pull request? `RuntimeConfig` is the new user-facing API in 2.0 added in #11378. Until now, however, it's been dead code. This patch uses `RuntimeConfig` in `SessionState` and exposes that through the `SparkSession`. ## How was this patch tested? New test in `SQLContextSuite`. Author: Andrew Or <andrew@databricks.com> Closes #12669 from andrewor14/use-runtime-conf.

| | | | | | | | | | | | ## What changes were proposed in this pull request? This patch changes UnresolvedFunction and UnresolvedGenerator to use a FunctionIdentifier rather than just a String for function name. Also changed SessionCatalog to accept FunctionIdentifier in lookupFunction. ## How was this patch tested? Updated related unit tests. Author: Reynold Xin <rxin@databricks.com> Closes #12659 from rxin/SPARK-14888.

| | | | | | | | | | | | | | | | | | | ## 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?

* [SPARK-14885][SQL] When creating a CatalogColumn, we should use the ↵Yin Huai2016-04-242-3/+3
| | | | | | | | | | | | | | | catalogString of a DataType object. ## What changes were proposed in this pull request? Right now, the data type field of a CatalogColumn is using the string representation. When we create this string from a DataType object, there are places where we use simpleString instead of catalogString. Although catalogString is the same as simpleString right now, it is still good to use catalogString. So, we will not silently introduce issues when we change the semantic of simpleString or the implementation of catalogString. ## How was this patch tested? Existing tests.

* [SPARK-14833][SQL][STREAMING][TEST] Refactor StreamTests to test for source ↵Tathagata Das2016-04-232-197/+233
| | | | | | | | | | | | | | | | | | | | | | | | | fault-tolerance correctly. ## What changes were proposed in this pull request? Current StreamTest allows testing of a streaming Dataset generated explicitly wraps a source. This is different from the actual production code path where the source object is dynamically created through a DataSource object every time a query is started. So all the fault-tolerance testing in FileSourceSuite and FileSourceStressSuite is not really testing the actual code path as they are just reusing the FileStreamSource object. This PR fixes StreamTest and the FileSource***Suite to test this correctly. Instead of maintaining a mapping of source --> expected offset in StreamTest (which requires reuse of source object), it now maintains a mapping of source index --> offset, so that it is independent of the source object. Summary of changes - StreamTest refactored to keep track of offset by source index instead of source - AddData, AddTextData and AddParquetData updated to find the FileStreamSource object from an active query, so that it can work with sources generated when query is started. - Refactored unit tests in FileSource***Suite to test using DataFrame/Dataset generated with public, rather than reusing the same FileStreamSource. This correctly tests fault tolerance. The refactoring changed a lot of indents in FileSourceSuite, so its recommended to hide whitespace changes with this - https://github.com/apache/spark/pull/12592/files?w=1 ## How was this patch tested? Refactored unit tests. Author: Tathagata Das <tathagata.das1565@gmail.com> Closes #12592 from tdas/SPARK-14833.

As we can't estimate the size of `ObjectType`, we throw an `UnsupportedOperationException` if trying to do that. We should set a default size for `ObjectType` to avoid this failure. ## How was this patch tested? `DatasetSuite`.

* [SPARK-14865][SQL] Better error handling for view creation.Reynold Xin2016-04-233-71/+100
| | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This patch improves error handling in view creation. CreateViewCommand itself will analyze the view SQL query first, and if it cannot successfully analyze it, throw an AnalysisException. In addition, I also added the following two conservative guards for easier identification of Spark bugs: 1. If there is a bug and the generated view SQL cannot be analyzed, throw an exception at runtime. Note that this is not an AnalysisException because it is not caused by the user and more likely indicate a bug in Spark. 2. SQLBuilder when it gets an unresolved plan, it will also show the plan in the error message. I also took the chance to simplify the internal implementation of CreateViewCommand, and *removed* a fallback path that would've masked an exception from before. ## How was this patch tested? 1. Added a unit test for the user facing error handling. 2. Manually introduced some bugs in Spark to test the internal defensive error handling. 3. Also added a test case to test nested views (not super relevant). Author: Reynold Xin <rxin@databricks.com> Closes #12633 from rxin/SPARK-14865.
* [SPARK-14869][SQL] Don't mask exceptions in ResolveRelationsReynold Xin2016-04-239-17/+25
| | | | | | | | | | | | ## 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.

| | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? When FileSourceStrategy is used, record reader is created which incurs a NN call internally. Later in OrcRelation.unwrapOrcStructs, it ends ups reading the file information to get the ObjectInspector. This incurs additional NN call. It would be good to avoid this additional NN call (specifically for partitioned datasets). Added OrcRecordReader which is very similar to OrcNewInputFormat.OrcRecordReader with an option of exposing the ObjectInspector. This eliminates the need to look up the file later for generating the object inspector. This would be specifically be useful for partitioned tables/datasets. ## How was this patch tested?

* [SPARK-14832][SQL][STREAMING] Refactor DataSource to ensure schema is ↵Tathagata Das2016-04-224-49/+116
| | | | | | | | | | | | | | | | | | | | | inferred only once when creating a file stream ## What changes were proposed in this pull request? When creating a file stream using sqlContext.write.stream(), existing files are scanned twice for finding the schema - Once, when creating a DataSource + StreamingRelation in the DataFrameReader.stream() - Again, when creating streaming Source from the DataSource, in DataSource.createSource() Instead, the schema should be generated only once, at the time of creating the dataframe, and when the streaming source is created, it should just reuse that schema The solution proposed in this PR is to add a lazy field in DataSource that caches the schema. Then streaming Source created by the DataSource can just reuse the schema. ## How was this patch tested? Refactored unit tests. Author: Tathagata Das <tathagata.das1565@gmail.com> Closes #12591 from tdas/SPARK-14832.
* [SPARK-14582][SQL] increase parallelism for small tablesDavies Liu2016-04-222-1/+9
| | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This PR try to increase the parallelism for small table (a few of big files) to reduce the query time, by decrease the maxSplitBytes, the goal is to have at least one task per CPU in the cluster, if the total size of all files is bigger than openCostInBytes * 2 * nCPU. For example, a small/medium table could be used as dimension table in huge query, this will be useful to reduce the time waiting for broadcast. ## How was this patch tested? Existing tests. Author: Davies Liu <davies@databricks.com> Closes #12344 from davies/more_partition.
* [SPARK-14796][SQL] Add spark.sql.optimizer.inSetConversionThreshold config ↵Dongjoon Hyun2016-04-225-7/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | option. ## What changes were proposed in this pull request? Currently, `OptimizeIn` optimizer replaces `In` expression into `InSet` expression if the size of set is greater than a constant, 10. This issue aims to make a configuration `spark.sql.optimizer.inSetConversionThreshold` for that. After this PR, `OptimizerIn` is configurable. ```scala scala> sql("select a in (1,2,3) from (select explode(array(1,2)) a) T").explain() == Physical Plan == WholeStageCodegen : +- Project [a#7 IN (1,2,3) AS (a IN (1, 2, 3))#8] : +- INPUT +- Generate explode([1,2]), false, false, [a#7] +- Scan OneRowRelation[] scala> sqlContext.setConf("spark.sql.optimizer.inSetConversionThreshold", "2") scala> sql("select a in (1,2,3) from (select explode(array(1,2)) a) T").explain() == Physical Plan == WholeStageCodegen : +- Project [a#16 INSET (1,2,3) AS (a IN (1, 2, 3))#17] : +- INPUT +- Generate explode([1,2]), false, false, [a#16] +- Scan OneRowRelation[] ``` ## How was this patch tested? Pass the Jenkins tests (with a new testcase) Author: Dongjoon Hyun <dongjoon@apache.org> Closes #12562 from dongjoon-hyun/SPARK-14796.
* [SPARK-14669] [SQL] Fix some SQL metrics in codegen and added moreDavies Liu2016-04-229-31/+99
| | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? 1. Fix the "spill size" of TungstenAggregate and Sort 2. Rename "data size" to "peak memory" to match the actual meaning (also consistent with task metrics) 3. Added "data size" for ShuffleExchange and BroadcastExchange 4. Added some timing for Sort, Aggregate and BroadcastExchange (this requires another patch to work) ## How was this patch tested? Existing tests. ![metrics](https://cloud.githubusercontent.com/assets/40902/14573908/21ad2f00-030d-11e6-9e2c-c544f30039ea.png) Author: Davies Liu <davies@databricks.com> Closes #12425 from davies/fix_metrics.
* [SPARK-14791] [SQL] fix risk condition between broadcast and subqueryDavies Liu2016-04-224-15/+34
| | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? SparkPlan.prepare() could be called in different threads (BroadcastExchange will call it in a thread pool), it only make sure that doPrepare() will only be called once, the second call to prepare() may return earlier before all the children had finished prepare(). Then some operator may call doProduce() before prepareSubqueries(), `null` will be used as the result of subquery, which is wrong. This cause TPCDS Q23B returns wrong answer sometimes. This PR added synchronization for prepare(), make sure all the children had finished prepare() before return. Also call prepare() in produce() (similar to execute()). Added checking for ScalarSubquery to make sure that the subquery has finished before using the result. ## How was this patch tested? Manually tested with Q23B, no wrong answer anymore. Author: Davies Liu <davies@databricks.com> Closes #12600 from davies/fix_risk.
* [SPARK-14763][SQL] fix subquery resolutionDavies Liu2016-04-227-49/+173
| | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Currently, a column could be resolved wrongly if there are columns from both outer table and subquery have the same name, we should only resolve the attributes that can't be resolved within subquery. They may have same exprId than other attributes in subquery, so we should create alias for them. Also, the column in IN subquery could have same exprId, we should create alias for them. ## How was this patch tested? Added regression tests. Manually tests TPCDS Q70 and Q95, work well after this patch. Author: Davies Liu <davies@databricks.com> Closes #12539 from davies/fix_subquery.
