Surendra Singh Lilhore commented on YARN-4783:
----------------------------------------------
Thanks [~jlowe] for comment..
bq. in the general case we can't leave it around forever because it will
eventually expire on its own. Therefore we can't support arbitrary delays
between the application completing and the log aggregation starting.
Agree with you.
