Weiwei Yang commented on YARN-6596:
-----------------------------------
Thanks [~asuresh] for the quick response
bq. As per the RM failover protocol, once the AM has detected that the RM has
failed over, am AM would have to re-register
That should address my concern, thanks. Does this work on AM failure too? I
don't see this info gets added into {{ApplicationSubmissionContext}}, not sure
if it can be retrieved when RM needs to relaunch an AM. Just want to make sure
this works in every possible failure paths.
