* [SPARK-14542][CORE] PipeRDD should allow configurable buffer size for…Sital Kedia2016-05-101-0/+4
| | | | | | | | | | | | | ## What changes were proposed in this pull request? Currently PipedRDD internally uses PrintWriter to write data to the stdin of the piped process, which by default uses a BufferedWriter of buffer size 8k. In our experiment, we have seen that 8k buffer size is too small and the job spends significant amount of CPU time in system calls to copy the data. We should have a way to configure the buffer size for the writer. ## How was this patch tested? Ran PipedRDDSuite tests. Author: Sital Kedia <skedia@fb.com> Closes #12309 from sitalkedia/bufferedPipedRDD.

* [SPARK-14952][CORE][ML] Remove methods that were deprecated in 1.6.0Herman van Hovell2016-04-301-0/+5
| | | | | | | | | | | | | | | | | | #### What changes were proposed in this pull request? This PR removes three methods the were deprecated in 1.6.0: - `PortableDataStream.close()` - `LinearRegression.weights` - `LogisticRegression.weights` The rationale for doing this is that the impact is small and that Spark 2.0 is a major release. #### How was this patch tested? Compilation succeded. Author: Herman van Hovell <hvanhovell@questtec.nl> Closes #12732 from hvanhovell/SPARK-14952.
* [SPARK-14511][BUILD] Upgrade genjavadoc to latest upstreamJakob Odersky2016-04-291-3/+7
| | | | | | | | | | | | | ## What changes were proposed in this pull request? In the past, genjavadoc had issues with package private members which led the spark project to use a forked version. This issue has been fixed upstream (typesafehub/genjavadoc#70) and a release is available for scala versions 2.10, 2.11 **and 2.12**, hence a forked version for spark is no longer necessary. This pull request updates the build configuration to use the newest upstream genjavadoc. ## How was this patch tested? The build was run `sbt unidoc`. During the process javadoc emits some errors on the generated java stubs, however these errors were also present before the upgrade. Furthermore, the produced html is fine. Author: Jakob Odersky <jakob@odersky.com> Closes #12707 from jodersky/SPARK-14511-genjavadoc.

* [SPARK-14654][CORE] New accumulator APIWenchen Fan2016-04-281-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This PR introduces a new accumulator API which is much simpler than before: 1. the type hierarchy is simplified, now we only have an `Accumulator` class 2. Combine `initialValue` and `zeroValue` concepts into just one concept: `zeroValue` 3. there in only one `register` method, the accumulator registration and cleanup registration are combined. 4. the `id`,`name` and `countFailedValues` are combined into an `AccumulatorMetadata`, and is provided during registration. `SQLMetric` is a good example to show the simplicity of this new API. What we break: 1. no `setValue` anymore. In the new API, the intermedia type can be different from the result type, it's very hard to implement a general `setValue` 2. accumulator can't be serialized before registered. Problems need to be addressed in follow-ups: 1. with this new API, `AccumulatorInfo` doesn't make a lot of sense, the partial output is not partial updates, we need to expose the intermediate value. 2. `ExceptionFailure` should not carry the accumulator updates. Why do users care about accumulator updates for failed cases? It looks like we only use this feature to update the internal metrics, how about we sending a heartbeat to update internal metrics after the failure event? 3. the public event `SparkListenerTaskEnd` carries a `TaskMetrics`. Ideally this `TaskMetrics` don't need to carry external accumulators, as the only method of `TaskMetrics` that can access external accumulators is `private[spark]`. However, `SQLListener` use it to retrieve sql metrics. ## How was this patch tested? existing tests Author: Wenchen Fan <wenchen@databricks.com> Closes #12612 from cloud-fan/acc.

* [SPARK-14861][SQL] Replace internal usages of SQLContext with SparkSessionAndrew Or2016-04-251-0/+14
| | | | | | | | | | | | | | | | | | ## 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.
* [SPARK-14790] Always run scalastyle on sbt compile and testEric Liang2016-04-251-1/+83
| | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Sbt compile and test should also run scalastyle. This makes it less likely you forget to run scalastyle and fail in jenkins. Scalastyle results are cached for efficiency. This patch was originally written by ahirreddy; I just fixed it up to work with scalastyle 0.8.0. ## How was this patch tested? Tested manually with `build/sbt package`. Author: Eric Liang <ekl@databricks.com> Closes #12555 from ericl/scalastyle.
* [SPARK-14807] Create a compatibility moduleYin Huai2016-04-221-3/+3

This PR creates a compatibility module in sql (called `hive-1-x-compatibility`), which will host HiveContext in Spark 2.0 (moving HiveContext to here will be done separately). This module is not included in assembly because only users who still want to access HiveContext need it. ## How was this patch tested?

Before this PR, we create accumulators at driver side(and register them) and send them to executor side, then we create `TaskMetrics` with these accumulators at executor side. After this PR, we will create `TaskMetrics` at driver side and send it to executor side, so that we can create accumulators inside `TaskMetrics` directly, which is cleaner. ## How was this patch tested? existing tests.

This PR is a follow up for https://github.com/apache/spark/pull/12417, now we always track input/output/shuffle metrics in spark JSON protocol and status API.

* [SPARK-14628][CORE] Simplify task metrics by always tracking read/write metricsReynold Xin2016-04-151-1/+4
| | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Part of the reason why TaskMetrics and its callers are complicated are due to the optional metrics we collect, including input, output, shuffle read, and shuffle write. I think we can always track them and just assign 0 as the initial values. It is usually very obvious whether a task is supposed to read any data or not. By always tracking them, we can remove a lot of map, foreach, flatMap, getOrElse(0L) calls throughout Spark. This patch also changes a few behaviors. 1. Removed the distinction of data read/write methods (e.g. Hadoop, Memory, Network, etc). 2. Accumulate all data reads and writes, rather than only the first method. (Fixes SPARK-5225) ## How was this patch tested? existing tests. This is bases on https://github.com/apache/spark/pull/12388, with more test fixes.

* [SPARK-14596][SQL] Remove not used SqlNewHadoopRDD and some more unused importshyukjinkwon2016-04-141-5/+0
| | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? Old `HadoopFsRelation` API includes `buildInternalScan()` which uses `SqlNewHadoopRDD` in `ParquetRelation`. Because now the old API is removed, `SqlNewHadoopRDD` is not used anymore. So, this PR removes `SqlNewHadoopRDD` and several unused imports. This was discussed in https://github.com/apache/spark/pull/12326. ## How was this patch tested? Several related existing unit tests and `sbt scalastyle`. Author: hyukjinkwon <gurwls223@gmail.com> Closes #12354 from HyukjinKwon/SPARK-14596.

| | | | | | | | | | | | | | ## What changes were proposed in this pull request? When we first introduced Aggregators, we required the user of Aggregators to (implicitly) specify the encoders. It would actually make more sense to have the encoders be specified by the implementation of Aggregators, since each implementation should have the most state about how to encode its own data type. Note that this simplifies the Java API because Java users no longer need to explicitly specify encoders for aggregators. ## How was this patch tested? Updated unit tests.

* [SPARK-14437][CORE] Use the address that NettyBlockTransferService listens ↵Shixiong Zhu2016-04-081-0/+3
| | | | | | | | | | | | | | | | | | | to create BlockManagerId ## What changes were proposed in this pull request? Here is why SPARK-14437 happens: BlockManagerId is created using NettyBlockTransferService.hostName which comes from `customHostname`. And `Executor` will set `customHostname` to the hostname which is detected by the driver. However, the driver may not be able to detect the correct address in some complicated network (Netty's Channel.remoteAddress doesn't always return a connectable address). In such case, `BlockManagerId` will be created using a wrong hostname. To fix this issue, this PR uses `hostname` provided by `SparkEnv.create` to create `NettyBlockTransferService` and set `NettyBlockTransferService.hostname` to this one directly. A bonus of this approach is NettyBlockTransferService won't bound to `0.0.0.0` which is much safer. ## How was this patch tested? Manually checked the bound address using local-cluster. Author: Shixiong Zhu <shixiong@databricks.com> Closes #12240 from zsxwing/SPARK-14437.
* [SPARK-13048][ML][MLLIB] keepLastCheckpoint option for LDA EM optimizerJoseph K. Bradley2016-04-071-0/+3
| | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? The EMLDAOptimizer should generally not delete its last checkpoint since that can cause failures when DistributedLDAModel methods are called (if any partitions need to be recovered from the checkpoint). This PR adds a "deleteLastCheckpoint" option which defaults to false. This is a change in behavior from Spark 1.6, in that the last checkpoint will not be removed by default. This involves adding the deleteLastCheckpoint option to both spark.ml and spark.mllib, and modifying PeriodicCheckpointer to support the option. This also: * Makes MLlibTestSparkContext extend TempDirectory and set the checkpointDir to tempDir * Updates LibSVMRelationSuite because of a name conflict with "tempDir" (and fixes a bug where it failed to delete a temp directory) * Adds a MIMA exclude for DistributedLDAModel constructor, which is already ```private[clustering]``` ## How was this patch tested?

* [SPARK-13713][SQL] Migrate parser from ANTLR3 to ANTLR4Herman van Hovell2016-03-282-2/+12
| | | | | | | | | | | | | | | | | | | | | | ### What changes were proposed in this pull request? The current ANTLR3 parser is quite complex to maintain and suffers from code blow-ups. This PR introduces a new parser that is based on ANTLR4. This parser is based on the [Presto's SQL parser](https://github.com/facebook/presto/blob/master/presto-parser/src/main/antlr4/com/facebook/presto/sql/parser/SqlBase.g4). The current implementation can parse and create Catalyst and SQL plans. Large parts of the HiveQl DDL and some of the DML functionality is currently missing, the plan is to add this in follow-up PRs. This PR is a work in progress, and work needs to be done in the following area's: - [x] Error handling should be improved. - [x] Documentation should be improved. - [x] Multi-Insert needs to be tested. - [ ] Naming and package locations. ### How was this patch tested? Catalyst and SQL unit tests. Author: Herman van Hovell <hvanhovell@questtec.nl> Closes #11557 from hvanhovell/ngParser.
