Rohith Sharma K S commented on YARN-6872:
-----------------------------------------
Continue on label validation failure is good if AM is already launched. But
what will happens if app is in accepted state and recovered?
If application is not killed/failed during recovery, then need to handle in
RMAppAttemptImpl schedule transition where AM RR is sent to scheduler.
> Ensure apps could run given NodeLabels are disabled post RM switchover/restart

> Post YARN-6031, few apps could be failed during recovery provided they had
> some label requirements for AM and labels were disable post RM
> restart/switchover. As discussed in YARN-6031, its better to run such apps as
> it may be long running apps as well.
