[jira] [Comment Edited] (SPARK-12945) ERROR LiveListenerBus:
Listener JobProgressListener threw an exception
[ https://issues.apache.org/jira/browse/SPARK-12945?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15377322#comment-15377322 ]

----------------------------------------------------------------
I got that error too multiple times from different jobs. I had UI disabled, so that might not be the reason. What helped was to reduce a number of partitions: I just coalesced my dataset in the beginning of the program from over 30.000 partitions to 300, and everything worked fine (but slowly).
