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.)
