GitHub user rxin opened a pull request:
https://github.com/apache/spark/pull/9175
Minor cleanup of ShuffleMapStage.outputLocs code.
I was looking at this code and found the documentation to be insufficient.
I added more documentation, and refactored some relevant code path slightly to
improve encapsulation. There are more that I want to do, but I want to get
these changes in before doing more work.
My goal is to reduce exposing internal fields directly in ShuffleMapStage
to improve encapsulation. After this change, DAGScheduler no longer directly
writes outputLocs. There are still 3 places that reads outputLocs directly, but
we can change those later.
