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

["Ruslan Dautkhanov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-2141?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14593802#comment-14593802 ] 

Ruslan Dautkhanov commented on SPARK-2141:
------------------------------------------

Would be gread to have this implemented in PySpark as well. 
Very handy in setups like Jupyter where we have a lot of RDDs declared in a Spark Notebook, 
and its hard to tell where is memory consumed. UnpersistAll isn't really a solution, as if we rerun
all the cells, we're back to square one.
