Robert Joseph Evans updated MAPREDUCE-3312:
-------------------------------------------
Attachment: MR-3312.txt
This patch adds in a new state to TaskAttemptImpl. The state is triggered if a
TA_KILL is received before the result of the CONTAINER_LAUNCH is known. It
will not issue the CONTAINER_CLEANUP event until the the result of the
CONTAINER_LAUNCH is known. I chose TaskAttemptImpl because it is tied 1 to 1
to a container, and in the current code it is the only place to launch or
cleanup a container.
Ideally I would also like to make ContainerLauncherImpl safe to have containers
launched and cleaned up in any order, but MAPREDUCE-3333 is possibly going to
touch the same code, and because changes to truly make it safe would require
significant changes I thought it best to hold off on it. If that is something
that you want I have the beginnings of a patch for it that I could also add in
fairly quickly.

> 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.
