Robert Joseph Evans updated MAPREDUCE-3312:
-------------------------------------------
Attachment: MR-3312.txt
This version of the patch will not change the state machine, instead it updates
the ContaienrLauncherImpl to keep track of state for each container and do the
right thing.
This removes the need for ContainerRemoteLaunchEvent.equals which appears to
have already been changed from its original implementation. Originally it was
used to remove all related events from the queue.
> Make MR AM not send a stopContainer w/o corresponding start container

> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.0, 0.24.0
> Reporter: Robert Joseph Evans
> Assignee: Robert Joseph Evans
> Fix For: 0.23.1

> This is a follow on to MAPREDUCE-3274. It is possible, although rare, for
> the MR AM to send a stop container before it sends a start container. This
> needs to stop that from happening. If a stop is found first it should
> prevent the start from being sent. It tries to do this, but only if the stop
> is currently pending.
