Charles Allen commented on SPARK-16798:
---------------------------------------
I am definitely running a *modified* 2.0.0, but modifications are in the
scheduler, not the RDD paths.
Right now I'm running 1.5.2_2.11 through the deployment system to get as close
to apples-to-apples as I can (and so that workflows can be swapped between the
two ad-hoc)
