Jun Gong commented on YARN-4770:
--------------------------------
Thanks [~vinodkv] for reporting the issue. The patch in YARN-3998 should have
handled this case.

The relaunch feature needs to work across NM restarts, so we should save the
retry-context and policy per container into the state-store and reload it for
continue relaunching after NM restart.
{quote}
As [~vvasudev] said, "The container retry policy details are already stored in
the state-store as part of the ContainerLaunchContext", so we do not need care
it.

We should also handle restarting of any containers that may have crashed during
the NM reboot.

If container crashed during the NM reboot, container would transit to
RELAUNCHING state. I will check it again.
> Auto-restart of containers should work across NM restarts.

> on YARN-3998. Need to take care of two things:
> - The relaunch feature needs to work across NM restarts, so we should save
> the retry-context and policy per container into the state-store and reload it
> for continue relaunching after NM restart.
> - We should also handle restarting of any containers that may have crashed
> during the NM reboot.
