Patrick Wendell commented on SPARK-2585:
----------------------------------------
Unfortunately after a lot of effort we still can't get the test times down on
this one and it's still unclear whether it will cause performance regressions.
Since this isn't particularly critical from a user perspective (it's mostly
about simplifying internals) I think it's best to punt this to 1.2. One
unfortunate thing is that it means SPARK-2546 will remain broken in 1.1.

> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Reporter: Patrick Wendell
> Assignee: Josh Rosen
> Priority: Critical

> This is a follow up to SPARK-2521 and should close SPARK-2546 (provided the
> implementation does not use shared conf objects). We no longer need to
> specially broadcast the Hadoop configuration since we are broadcasting RDD
> data anyways.
