Apache Spark reassigned SPARK-14699:
------------------------------------
Assignee: (was: Apache Spark)
> Driver is marked as failed even it runs successfully
> ----------------------------------------------------
>
> Key: SPARK-14699
> URL: https://issues.apache.org/jira/browse/SPARK-14699
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.6.0, 1.6.1
> Environment: Standalone deployment
> Reporter: Huiqiang Liu
>
> We recently upgraded Spark from 1.5.2 to 1.6.0 and found that all batch jobs
> are marked as failed.
> To address this issue, we wrote a simple test application which just sum up
> from 1 to 10000 and it is marked as failed even though its result was correct.
> Here is the typical stderr message and there is "ERROR worker.WorkerWatcher:
> Lost connection to worker rpc" when driver exits.

> Since it looks like something related with rpc, we tested with Akka which was
> default before 1.6.0 by setting "spark.rpc=akka".
> Then the error message dismisses and a warning complains the same thing about
> disassociation with worker.
> It seems with Akka it waits another 5 seconds and that makes driver exists
> gracefully.

> This only occurs with standalone deployment since it is said DriverWrapper is
> only used in that cluster mode.
> https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/deploy/worker/DriverWrapper.scala#L43
> Typically it affects the '--supervise' usage for batch jobs, since they will
> be always considered as failed and get restarted again and again.
