----------------------------------
Resolution: Fixed

Fix Version/s: 1.5.0
> ReceiverTrackerSuite fails for maven build
> ------------------------------------------
>
> Key: SPARK-9479
> URL: https://issues.apache.org/jira/browse/SPARK-9479
> Project: Spark
> Issue Type: Bug
> Components: Streaming, Tests
> Reporter: Shixiong Zhu
> Assignee: Shixiong Zhu
> Fix For: 1.5.0
>
>
> The test failure is here:
> https://amplab.cs.berkeley.edu/jenkins/job/Spark-Master-Maven-with-YARN/3109/
> I saw the following exception in the log:
> {code}
> org.apache.spark.SparkException: Job aborted due to stage failure: Task
> serialization failed: java.lang.NullPointerException
> org.apache.spark.broadcast.TorrentBroadcast.<init>(TorrentBroadcast.scala:80)
> org.apache.spark.broadcast.TorrentBroadcastFactory.newBroadcast(TorrentBroadcastFactory.scala:34)
> org.apache.spark.broadcast.BroadcastManager.newBroadcast(BroadcastManager.scala:63)
> org.apache.spark.SparkContext.broadcast(SparkContext.scala:1297)
> org.apache.spark.scheduler.DAGScheduler.org$apache$spark$scheduler$DAGScheduler$$submitMissingTasks(DAGScheduler.scala:834)
> {code}
> This exception is because SparkEnv.get returns null.
> I found the maven build is different from the sbt build. The maven build will
> create all Suite classes at the beginning. `ReceiverTrackerSuite` creates
> StreamingContext (SparkContext) in the constructor. That means SparkContext
> is created very early. And the global SparkEnv will be set to null in the
> previous test. Therefore we saw the above exception when running `Receiver
> tracker - propagates rate limit` in `ReceiverTrackerSuite`. This test was
> added recently.
> Note: the previous tests in `ReceiverTrackerSuite` didn't use SparkContext
> actually, that's why we didn't see such failure before.
