Thomas Graves updated SPARK-22151:
----------------------------------
    Description: 
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
