Sunil G commented on YARN-6872:
-------------------------------
NM work preserving was off. Now I can see that resources are coming correctly.
However I am seeing an issue with Cluster Metrics. Its coming -ve or wrong
after RM restart. Even without node label disabled scenario, metrics are wrong.
I think it should be handled in another ticket as metrics calculation is wrong
after running app recovery and RM work preserving restart (when labels are
used).
Please suggest whether we need to include metrics issue also here.

> 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.
