DjvuLee commented on SPARK-21547:
---------------------------------
Yes, I agree that this has a relationship with the work, but doing nothing
about 3min is too long for a Streaming Application.
My proposal is try to let us to inspect whether the current cleaner strategy is
good enough.
> Spark cleaner cost too many time
