[jira] [Commented] (SPARK-5091) Hooks for PySpark tasks

    [ https://issues.apache.org/jira/browse/SPARK-5091?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15466855#comment-15466855 ] 

Semet commented on SPARK-5091:
------------------------------

It is a better option to use virtualenv and proper installation with pip, which is more scalable for Python jobs. Manipulating PYTHONPATH can lead so lot of strange behavior.

See [#14180|https://github.com/apache/spark/pull/14180].

> Currently, it's not convenient to add package on executor to PYTHONPATH (we did not assume the environment of driver an executor are identical). 
> It will be nice to have a hook to called before/after every tasks, then user could manipulate sys.path by pre-task-hooks.
