Till Rohrmann commented on FLINK-17075:
---------------------------------------
Hmm, the best solution which comes to my mind is to introduce a new
{{ExecuteState.DEPLOYED}} which is being set after the
{{TaskExecutor.submitTask}} acknowledges the task submission. The semantic of
this state would be that there is now something running on the the
{{TaskExecutor}}.

> Key: FLINK-17075
> URL: https://issues.apache.org/jira/browse/FLINK-17075
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination
> Affects Versions: 1.10.0, 1.11.0
> Reporter: Till Rohrmann
> Priority: Critical
> Fix For: 1.10.2, 1.12.0, 1.11.1

> In order to harden the TM and JM communication I suggest to let the
> {{TaskExecutor}} send the task statuses back to the {{JobMaster}} as part of
> the heartbeat payload (similar to FLINK-11059). This would allow to reconcile
> the states of both components in case that a status update message was lost
> as described by a user on the ML.
