Subject Re: PySpark Client

Hey Andrew,

Thanks for the response. Is this the issue you're referring to (the
duplicate linked there has an associated patch):
https://issues.apache.org/jira/browse/SPARK-5162 ?

Just to confirm that I understand this: with this patch, Python jobs can be
submitted to YARN, and a node from the cluster will act as the driver,
meaning that the Python version of the submission client vs. cluster
shouldn't be an issue?

Thanks,
Chris
