Rohith Sharma K S commented on YARN-3887:
-----------------------------------------

thanks [~sunilg] for updating patch.
Some comments
# The invocation {{rmContext.getStateStore().updateApplicationState(appState);}} is asynchronous.
So I feel stil there will be corner case would ocure where priority has set in scheduler but
not updated to RMStateSstore. So if any RM switch/Restart would end up in resulting in old
priority set.  I think this particular invocation should be should be synchronous like any
others API's  E.g: {{storeRMDelegationToken}}, {{storeRMDTMasterKey}}

> After YARN-2003, adding support to change priority of an application after submission.
This ticket will handle the server side implementation for same.
> A new RMAppEvent will be created to handle this, and will be common for all schedulers.
