Sunil G commented on YARN-6872:
-------------------------------
Thanks [~rohithsharma]
When new container requests comes, its been validated in
ApplicationMasterService#allocate and InvalidResourceRequestException is thrown
back to AM. Hence scheduler will not have problem. At most what could happen
is, AM container may never get scheduled and it may remain in scheduler queue
until admin corrects the pblm with labels. (enabled/disable)
> 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.
