Sandy Ryza commented on YARN-1697:
----------------------------------
I took a look at the state transitions and I think I know what's going on.
Running containers gets incremented in LaunchTransition and decremented in
ContainerDoneTransition, if the state it's transitioning from is
EXITED_WITH_FAILURE or EXITED_WITH_SUCCESS.
If a container goes directly from LOCALIZING to EXITED_WITH_FAILURE, it will
never go through the LaunchTransition, so the running containers will never be
incremented. But it will still be decremented.
