[jira] [Commented] (SPARK-2141) Add sc.getPersistentRDDs() to PySpark

["Shea Parkes (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-2141?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15665137#comment-15665137 ] 

Shea Parkes commented on SPARK-2141:
------------------------------------

This would have been nice to have today.  We wanted to clean up some cached interim RDDs from a mllib model fit, but there were no references to them in the python interpreter.  To get around this, we had to reach into the _jsc attribute and utilize the java-based getPersistentRDDs to get references to the dang RDDs (just long enough to unpersist them).
