Jian He commented on YARN-4597:
-------------------------------
bq. Will rerun and see if they are required… but in anycase, having them there
should be harmless right?
If the events should not happen in theory, I think we should not add it.
otherwise, it could possibly hide bugs..we should fix the source to not send
the events, instead of ignoring the events at receiver.
