> Running in yarn cluster mode and trying to set pythonpath via 
> spark.yarn.appMasterEnv.PYTHONPATH doesn't work.
> the yarn Client code looks at the env variables:
> val pythonPathStr = (sys.env.get("PYTHONPATH") ++ pythonPath)
> But when you set spark.yarn.appMasterEnv it puts it into the local env. 
> So the python path set in spark.yarn.appMasterEnv isn't properly set.
> You can work around if you are running in cluster mode by setting it on the 
> client like:
> PYTHONPATH=./addon/python/ spark-submit
