Siddharth Seth commented on YARN-579:
-------------------------------------
bq. The AppToken is stored in ContainerLaunchContext,not in Container, so
appToken should be set before ApplicationSubmissionContext is saved to help
RM-restart
bq. appToken is attempt specific. So it needs to be store per app attempt. So
it needs to be generated when app attempt is assigned a container and saved in
appAttemptStateData. Basically the code needs to be moved from AMLauncher to
the rmappattempimpl. AMLauncher will simply use the token from the attempt.
I believe this is being addressed in YARN-582.
Committing this patch. The latest test-patch can be ignored since the MR bit is
necessary for trunk to compile.

> Container is already persisted for helping RM restart. Instead of explicitly
> setting ApplicationToken in AM's env, if we change it to be in Container, we
> can avoid env and can also help restart.
