Pete Robbins commented on SPARK-9869:
-------------------------------------
My pull request build for https://issues.apache.org/jira/browse/SPARK-10431
failed with this error so I took a look. I think it's another timing issue
where the assert on the progress listener occurs before the asynchronous
notification thread has completed processing.
Something like this should fix it:
