---------------------------
Summary: CoarseGrainedExecutorBackend exits for irrelevant
DisassociatedEvent (was: ExecutorBackend exits for irrelevant
DisassociatedEvent)
> CoarseGrainedExecutorBackend exits for irrelevant DisassociatedEvent
> --------------------------------------------------------------------
>
> Key: SPARK-5268
> URL: https://issues.apache.org/jira/browse/SPARK-5268
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.2.0
> Reporter: Nan Zhu
>
> In CoarseGrainedExecutorBackend, we subscribe DisassociatedEvent in executor
> backend actor and exit the program upon receive such event...
> let's consider the following case
> The user may develop an Akka-based program which starts the actor with
> Spark's actor system and communicate with an external actor system (e.g. an
> Akka-based receiver in spark streaming which communicates with an external
> system) If the external actor system fails or disassociates with the actor
> within spark's system with purpose, we may receive DisassociatedEvent and the
> executor is restarted.
> This is not the expected behavior.....
