Thanks for the review. With task slots we have to be careful though,
because it is possible that slots become available after some time.

> URL: https://issues.apache.org/jira/browse/FLINK-3050
> Project: Flink
> Issue Type: Improvement
> Components: Distributed Runtime
> Affects Versions: 0.10.0
> Reporter: Ufuk Celebi

> Priority: Minor
> Fix For: 1.0.0
>
>
> In case of failures and configured execution retries, the job will be be
> restarted even in cases when the failure is not recoverable.
> We can add a custom Exception type like UnrecoverableFailure in order to
> suppress restarts in certain cases. The execution graph restart logic can
> check the failure type on recovery and skip the restarting.
> This Exception can be used both by the system and the user.
