[jira] [Commented] (SPARK-13587) Support virtualenv in PySpark
[ https://issues.apache.org/jira/browse/SPARK-13587?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16217115#comment-16217115 ]

------------------------------------------
To follow-up on my [earlier comment|https://issues.apache.org/jira/browse/SPARK-13587?focusedCommentId=15740419&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15740419], I created a [completely self-contained sample repo|https://github.com/massmutual/sample-pyspark-application] demonstrating a technique for bundling PySpark app dependencies in an isolated way. It's the technique that Ben, I, and several others discussed here in this JIRA issue.
https://github.com/massmutual/sample-pyspark-application
The approach has advantages (like letting you ship a completely isolated Python environment, so you don't even need Python installed on the workers) and disadvantages (requires YARN; increases job startup time). Hope some of you find the sample repo useful until Spark adds more "first-class" support for Python dependency isolation.

> Key: SPARK-13587

> Project: Spark
> Issue Type: New Feature
> Components: PySpark

> Currently, it's not easy for user to add third party python packages in pyspark.
> * One way is to using --py-files (suitable for simple dependency, but not suitable for complicated dependency, especially with transitive dependency)
> * Another way is install packages manually on each node (time wasting, and not easy to switch to different environment)
> Python has now 2 different virtualenv implementation. One is native virtualenv another is through conda. This jira is trying to migrate these 2 tools to distributed environment
