> Shutdown does not work because of incorrect logic in the AppMaster
> ------------------------------------------------------------------
>
> Key: APEXCORE-624
> URL: https://issues.apache.org/jira/browse/APEXCORE-624
> Project: Apache Apex Core
> Issue Type: Bug
> Reporter: Sanjay M Pujare
> Assignee: Sanjay M Pujare
> Priority: Minor
>
> com.datatorrent.stram.StreamingAppMasterService.execute() calculates
> numRequestedContainers incorrectly in some cases (e.g. RM container
> allocation failure) which prevents an application from shutting down when it
> is requested externally. An example is where we ask RM to remove previous
> container allocation request (where the count should be decremented but is
> NOT) and add a new one (where the count should be and IS incremented).
> Another example is the "alreadyAllocated" case where we release the container
> and still increment numRequestedContainers which seems wrong.
> This bug is showing up in multiple Apex deployments.
