[jira] [Commented] (SPARK-4049) Storage web UI "fraction cached" shows as > 100%

    [ https://issues.apache.org/jira/browse/SPARK-4049?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15035131#comment-15035131 ] 

Warren Wang commented on SPARK-4049:
------------------------------------

This issue is really annoying when the rdd is reused for many times. For a particular execution, the fraction cached will increase 1%-10% unreasonably and never return back to 100%. When the rdd is reused for hundred times, the fraction cached will eventually reach to 200%, on which situation the spark job will crash for no more memory to use. Hope this to be fixed.
