Jun Gong commented on YARN-5015:
--------------------------------

Attach a patch to add failure validity interval for container relaunch.

If we unify AM restart and container restart, it seems we need modify proto for 
*ApplicationSubmissionContextProto*: move *maxAppAttempts* and 
*attempt_failures_validity_interval* to *ContainerRetryContextProto* which is 
inside *ContainerLaunchContextProto*. And we need to specify AM container retry 
context. They will be incompatible change. Will it be a problem?

> We support AM restart and container restarts - however the two have slightly 
> different capabilities. We should unify them. There's no reason for them to 
> be different.
