[jira] [Created] (SAMZA-1549) Synchronization issue between heartbeat scheduler and job coordinator main thread during processor shutdown

Navina Ramesh created SAMZA-1549:
------------------------------------

             Summary: Synchronization issue between heartbeat scheduler and job coordinator main thread during processor shutdown
                 Key: SAMZA-1549
                 URL: https://issues.apache.org/jira/browse/SAMZA-1549
             Project: Samza
          Issue Type: Bug
            Reporter: Navina Ramesh
            Priority: Critical


The symptom for this problem has been described in SAMZA-1523. 
Please note: SAMZA-1402 calls for a complete refactor of the schedulers in the Azure JobCoordinator. However, refactor is done or not, we need to guarantee ordering when the stream processor is being shutdown. Shutdown of the processor should allow for safe shutdown of the jobcoordinator schedulers and clean-up the table entries.
