Saikat Kanjilal commented on SPARK-9487:
----------------------------------------
[~srowen] build/tests has passed in jenkins, what do you think? Should we
commit a little at a time to keep this moving forward or should I make the next
change, I prefer to create new pull requests for each unit test area that I fix
so my preference would be to commit this little change for ContextCleaner.
> Use the same num. worker threads in Scala/Python unit tests

> Project: Spark

> Affects Versions: 1.5.0

> In Python we use `local[4]` for unit tests, while in Scala/Java we use
> `local[2]` and `local` for some unit tests in SQL, MLLib, and other
> components. If the operation depends on partition IDs, e.g., random number
> generator, this will lead to different result in Python and Scala/Java. It
> would be nice to use the same number in all unit tests.
