Github user uce commented on the pull request: https://github.com/apache/flink/pull/1153#issuecomment-144979369 While working on FLINK-2804 I've noticed an issue: the user jars are only uploaded to the leading job manager at submission time and then are not available to the other job managers on recovery. A simple solution is to make the user jars available in the file state backend as well.
