Bikas Saha commented on YARN-1490:
----------------------------------
Also, no containers are allocated until the application actually registers and
so doing this upon app registration should be the same timeline-wise as doing
this during app submission.
> RM should optionally not kill all containers when an ApplicationMaster exits

> reconnect with old running containers, some may not want to. This should be
> an option.
