In this test, it calls `advanceTimeWithRealDelay(ssc, 2)` to run two batch jobs. However, one race condition is these two jobs can finish before the receiver is registered. Then `UpdateRateLimit` won't be sent to the receiver and `getDefaultBlockGeneratorRateLimit` cannot be updated.

Here are the logs related to this issue:
```

```
`advanceTimeWithRealDelay(ssc, 2)` triggered job 3000ms and 3500ms but the receiver was registered after job 3000ms and 3500ms finished.

So we should make sure the receiver online before running `advanceTimeWithRealDelay(ssc, 2)`.

[SPARK-10224] [STREAMING] Fix the issue that blockIntervalTimer won't call updateCurrentBuffer when stopping

`blockIntervalTimer.stop(interruptTimer = false)` doesn't guarantee calling `updateCurrentBuffer`. So it's possible that `blockIntervalTimer` will exit when `updateCurrentBuffer` is not empty. Then the data in `currentBuffer` will be lost.

To reproduce it, you can add `Thread.sleep(200)` in this line (https://github.com/apache/spark/blob/69c9c177160e32a2fbc9b36ecc52156077fca6fc/streaming/src/main/scala/org/apache/spark/streaming/util/RecurringTimer.scala#L100) and run `StreamingContexSuite`.
I cannot write a unit test to reproduce it because I cannot find an approach to force `RecurringTimer` suspend at this line for a few milliseconds.

There was a failure in Jenkins here: https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/41455/console

This PR updates RecurringTimer to make sure `stop(interruptTimer = false)` will call `callback` at least once after the `stop` method is called.

[SPARK-10663] Removed unnecessary invocation of DataFrame.toDF method. · 558e9c7e

Matt Hagen authored 9 years ago

The Scala example under the "Example: Pipeline" heading in this
document initializes the "test" variable to a DataFrame. Because test
is already a DF, there is not need to call test.toDF as the example
does in a subsequent line: model.transform(test.toDF). So, I removed
the extraneous toDF invocation.

[SPARK-10310] [SQL] Fixes script transformation field/line delimiters · 84f81e03

Zhichao Li authored 9 years ago

**Please attribute this PR to `Zhichao Li <zhichao.liintel.com>`.**

This PR is based on PR #8476 authored by zhichao-li. It fixes SPARK-10310 by adding field delimiter SerDe property to the default `LazySimpleSerDe`, and enabling default record reader/writer classes.

Currently, we only support `LazySimpleSerDe`, used together with `TextRecordReader` and `TextRecordWriter`, and don't support customizing record reader/writer using `RECORDREADER`/`RECORDWRITER` clauses. This should be addressed in separate PR(s).

[SPARK-10714] [SPARK-8632] [SPARK-10685] [SQL] Refactor Python UDF handling · a96ba40f

Reynold Xin authored 9 years ago

This patch refactors Python UDF handling:

1. Extract the per-partition Python UDF calling logic from PythonRDD into a PythonRunner. PythonRunner itself expects iterator as input/output, and thus has no dependency on RDD. This way, we can use PythonRunner directly in a mapPartitions call, or in the future in an environment without RDDs.
2. Use PythonRunner in Spark SQL's BatchPythonEvaluation.
3. Updated BatchPythonEvaluation to only use its input once, rather than twice. This should fix Python UDF performance regression in Spark 1.5.

There are a number of small cleanups I wanted to do when I looked at the code, but I kept most of those out so the diff looks small.

This basically implements the approach in https://github.com/apache/spark/pull/8833, but with some code moving around so the correctness doesn't depend on the inner workings of Spark serialization and task execution.

[SPARK-10672] [SQL] Do not fail when we cannot save the metadata of a data source table in a hive compatible way

https://issues.apache.org/jira/browse/SPARK-10672

With changes in this PR, we will fallback to same the metadata of a table in Spark SQL specific way if we fail to save it in a hive compatible way (Hive throws an exception because of its internal restrictions, e.g. binary and decimal types cannot be saved to parquet if the metastore is running Hive 0.13). I manually tested the fix with the following test in `DataSourceWithHiveMetastoreCatalogSuite` (`spark.sql.hive.metastore.version=0.13` and `spark.sql.hive.metastore.jars`=`maven`).

```
    test(s"fail to save metadata of a parquet table in hive 0.13") {
      withTempPath { dir =>
        withTable("t") {
          val path = dir.getCanonicalPath

          sql(
            s"""CREATE TABLE t USING $provider
               |OPTIONS (path '$path')
               |AS SELECT 1 AS d1, cast("val_1" as binary) AS d2
             """.stripMargin)

          sql(
            s"""describe formatted t
             """.stripMargin).collect.foreach(println)

          sqlContext.table("t").show
        }
      }
    }
  }
```

Without this fix, we will fail with the following error.
```

[SPARK-10750] [ML] ML Param validate should print better error information · 7104ee0e

Yanbo Liang authored 9 years ago

Currently when you set illegal value for params of array type (such as IntArrayParam, DoubleArrayParam, StringArrayParam), it will throw IllegalArgumentException but with incomprehensible error information.
Take ```VectorSlicer.setNames``` as an example:
```scala
val vectorSlicer = new VectorSlicer().setInputCol("features").setOutputCol("result")
// The value of setNames must be contain distinct elements, so the next line will throw exception.
vectorSlicer.setIndices(Array.empty).setNames(Array("f1", "f4", "f1"))
```
It will throw IllegalArgumentException as:
```
vectorSlicer_b3b4d1a10f43 parameter names given invalid value [Ljava.lang.String;798256c5.
java.lang.IllegalArgumentException: vectorSlicer_b3b4d1a10f43 parameter names given invalid value [Ljava.lang.String;798256c5.
```
We should distinguish the value of array type from primitive type at Param.validate(value: T), and we will get better error information.
```
vectorSlicer_3b744ea277b2 parameter names given invalid value [f1,f4,f1].
java.lang.IllegalArgumentException: vectorSlicer_3b744ea277b2 parameter names given invalid value [f1,f4,f1].

JIRA: https://issues.apache.org/jira/browse/SPARK-10446

Currently the method `join(right: DataFrame, usingColumns: Seq[String])` only supports inner join. It is more convenient to have it support other join types.

[SPARK-9821] [PYSPARK] pyspark-reduceByKey-should-take-a-custom-partitioner · 1cd67415

Holden Karau authored 9 years ago

from the issue:

In Scala, I can supply a custom partitioner to reduceByKey (and other aggregation/repartitioning methods like aggregateByKey and combinedByKey), but as far as I can tell from the Pyspark API, there's no way to do the same in Python.
Here's an example of my code in Scala:
weblogs.map(s => (getFileType(s), 1)).reduceByKey(new FileTypePartitioner(),_+_)
But I can't figure out how to do the same in Python. The closest I can get is to call repartition before reduceByKey like so:
weblogs.map(lambda s: (getFileType(s), 1)).partitionBy(3,hash_filetype).reduceByKey(lambda v1,v2: v1+v2).collect()
But that defeats the purpose, because I'm shuffling twice instead of once, so my performance is worse instead of better.

[SPARK-10649] [STREAMING] Prevent inheriting job group and irrelevant job description in streaming jobs

The job group, and job descriptions information is passed through thread local properties, and get inherited by child threads. In case of spark streaming, the streaming jobs inherit these properties from the thread that called streamingContext.start(). This may not make sense.

1. Job group: This is mainly used for cancelling a group of jobs together. It does not make sense to cancel streaming jobs like this, as the effect will be unpredictable. And its not a valid usecase any way, to cancel a streaming context, call streamingContext.stop()

2. Job description: This is used to pass on nice text descriptions for jobs to show up in the UI. The job description of the thread that calls streamingContext.start() is not useful for all the streaming jobs, as it does not make sense for all of the streaming jobs to have the same description, and the description may or may not be related to streaming.

The solution in this PR is meant for the Spark master branch, where local properties are inherited by cloning the properties. The job group and job description in the thread that starts the streaming scheduler are explicitly removed, so that all the subsequent child threads does not inherit them. Also, the starting is done in a new child thread, so that setting the job group and description for streaming, does not change those properties in the thread that called streamingContext.start().

[SPARK-7989] [SPARK-10651] [CORE] [TESTS] Increase timeout to fix flaky tests · ebbf85f0

zsxwing authored 9 years ago

I noticed only one block manager registered with master in an unsuccessful build (https://amplab.cs.berkeley.edu/jenkins/job/Spark-Master-SBT/AMPLAB_JENKINS_BUILD_PROFILE=hadoop2.2,label=spark-test/3534/)
```
15/09/16 13:02:30.981 pool-1-thread-1-ScalaTest-running-BroadcastSuite INFO SparkContext: Running Spark version 1.6.0-SNAPSHOT
...
15/09/16 13:02:38.133 sparkDriver-akka.actor.default-dispatcher-19 INFO BlockManagerMasterEndpoint: Registering block manager localhost:48196 with 530.3 MB RAM, BlockManagerId(0, localhost, 48196)
```
In addition, the first block manager needed 7+ seconds to start. But the test expected 2 block managers so it failed.

However, there was no exception in this log file. So I checked a successful build (https://amplab.cs.berkeley.edu/jenkins/job/Spark-Master-SBT/3536/AMPLAB_JENKINS_BUILD_PROFILE=hadoop2.2,label=spark-test/) and it needed 4-5 seconds to set up the local cluster:
```

...
15/09/16 18:11:30.838 sparkDriver-akka.actor.default-dispatcher-20 INFO BlockManagerMasterEndpoint: Registering block manager localhost:54202 with 530.3 MB RAM, BlockManagerId(1, localhost, 54202)

```
In this build, the first block manager needed only 3+ seconds to start.

Comparing these two builds, I guess it's possible that the local cluster in `BroadcastSuite` cannot be ready in 10 seconds if the Jenkins worker is busy. So I just increased the timeout to 60 seconds to see if this can fix the issue.
