Bilwa S T updated MAPREDUCE-7308:
---------------------------------
Description: In RMContainerReuseRequestor whenever containerAssigned is
called it checks if allocated container can be reused. This always returns
false as the map is getting cleared on makeRemoteRequest. I think container can
be removed from containersToReuse map once its used. (was: In
RMContainerReuseRequestor whenever containerAssigned is called it checks if
allocated container can be reused. This always returns false as the map is
getting cleared on makeRemoteRequest. I think there is no need to clear the map
as container will be removed from containersToReuse map once its used.)
> Containers never get reused as containersToReuse map gets cleared on
> makeRemoteRequest
