[jira] [Commented] (SPARK-22151) PYTHONPATH not picked up from the spark.yarn.appMasterEnv properly

["Saisai Shao (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-22151?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16183581#comment-16183581 ] 

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}}.

>             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
