Jian He commented on YARN-5762:
-------------------------------
[~raviprak], instead of ignoring the exception at server, I think we should
fix the caller (AggregatedLogDeletionService) to not make a call for each
application to check its state, this is also an expensive loop to RM. Instead,
it can make one call to get all application reports and check each app's state.
your opinion ?
