> Project: Flink
> Issue Type: Bug
> Reporter: Till Rohrmann
>
> In case of a JobManager restart, which can happen due to an uncaught
> exception, the JobManager is restarted. However, connected TaskManager are
> not informed about the disconnection and continue sending messages to a
> JobManager with a reseted state.
> TaskManager should be informed about a possible restart and cleanup their own
> state in such a case. Afterwards, they can try to reconnect to a restarted
> JobManager.
