Saisai Shao commented on SPARK-22151:
-------------------------------------
Checking the Yarn client code, looks like there's specific code to handle
{{PYTHONPATH}}, but not for {{spark.yarn.appMasterEnv.PYTHONPATH}}.
> PYTHONPATH not picked up from the spark.yarn.appMasterEnv properly
> ------------------------------------------------------------------

> Key: SPARK-22151
> URL: https://issues.apache.org/jira/browse/SPARK-22151
> Project: Spark
> Issue Type: Bug
> Components: YARN
> Affects Versions: 2.1.1
> Reporter: Thomas Graves
>
> the 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
