----------------------------------------------
Summary: Fix race condition when stopping StreamProcessor.
Key: SAMZA-1665
URL: https://issues.apache.org/jira/browse/SAMZA-1665
Project: Samza
Issue Type: Bug
Reporter: Shanthoosh Venkataraman
Assignee: Shanthoosh Venkataraman
When the user thread stops the streamProcessor and onNewJobModelExpired event
is executed from debounce thread at the same time, we observe the following
issue:
A. User thread stops the StreamProcessor
B. Before ZkJobCoordinator is shutdown, onNewJobModelExpired is executed from
debounce thread(which spawns a new container).
C. User thread stops the ZkJobCoordinator.
After the StreamProcessor shutdown sequence returns, container thread is alive
and zkJobCoordinator is dead. This results in a orphaned container when
stopping stream processor. We were able reproduce this locally.
