Nan Zhu created SPARK-5268:
------------------------------
Summary: ExecutorBackend 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.....
