> 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.
