> Key: FLINK-13452
> URL: https://issues.apache.org/jira/browse/FLINK-13452
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.9.0, 1.10.0
> Reporter: Gary Yao
> Assignee: Yun Tang
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 1.9.0
>
> Attachments: jobmanager.log
>
>
> The job does not recover if a checkpoint cannot be read and
> {{jobmanager.execution.failover-strategy}} is set to _"region"_.
> *Analysis*
> The {{RestartCallback}} created by
> {{AdaptedRestartPipelinedRegionStrategyNG}} throws a \{{RuntimeException}} if
> no checkpoints could be read. When the restart is invoked in a separate
> thread pool, the exception is swallowed. See:

> *Expected behavior*
> * Job should restart
