> This is a bug in https://github.com/apache/flink/pull/1153.
> In case of multiple job managers, the user jars need to be accessible by all job managers
(including those who arrive later).
> Since #1153 requires the file state backend to be configured, the simplest solution is
to make the blob server aware of the configured recovery mode and put/get/delete the user
jars from the file state backend as well.
