>
> A previous fix (for APEXCORE-624) has introduced a regression where
> numRequestedContainers inside StreamingAppMasterService.execute() becomes
> negative because instead of incrementing numRequestedContainers it is being
> decremented under certain conditions as follows:
> While processing the YARN response of container allocation/release request,
> numRequestContainers is decremented by newAllocatedContainers.size()
> (correctly). However in case of (alreadyAllocated == true) the decrement
> should be undone by incrementing numRequestContainers (i.e.
> numRequestContainers++). However the current code is decrementing again (i.e.
> numRequestContainers--) on line 886
