----------------------------------------
Summary: 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: Critical
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.
