Sean Owen commented on SPARK-21547:
-----------------------------------

It depends on your app, what's in your closure, etc. I'm not sure what problem this causes
you.
"Look into X" isn't suitable as a JIRA. I think this would have to be paired with some hint
about what the issue is or how it could be addressed.

> Spark Streaming sometime cost so many time deal with cleaning, and this can become worse
when enable the dynamic allocation.
> I post the Driver's Log in the following comments, we can find that the cleaner costs
more than 2min.
