Varun Saxena commented on YARN-5297:
------------------------------------
[~djp], should we be removing the audit log ? Typically in production, audit
logs will go into a separate log file. And some people may use it as an input
in some of their tools as well. We in our company do not use it but are we sure
this audit log wont be useful to any of the users ?
Moreover, ApplicationMasterNotRegisteredException is thrown from
ApplicationMasterService#finishApplicationMaster as well. We will have 3 logs
in this flow as well.
> Avoid printing a stack trace when recovering an app after the RM restarts
