-------------------------------------
Assignee: Matthias Pohl
> Corrupted job-local HA data causes cluster-wide failover
> --------------------------------------------------------
>
> Key: FLINK-40553
> URL: https://issues.apache.org/jira/browse/FLINK-40553
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 2.3.0, 2.2.1, 2.4.0
> Reporter: Matthias Pohl
> Assignee: Matthias Pohl
> Priority: Major
>
> There are two code paths that can cause a cluster-wide failover if the HA
> data for a single job is corrupted in some way.
> One example was where the ExecutionPlan files got deleted causing a
> {{FileNotFoundException}} when recovering the job. That triggered a
> JobManager failover.
> A similar issue can appear when reading the JobResultStore entry files. The
> parsing happens in a single command for all files. One file failing to be
> retrieved results in the entire JobManager to fail over.
> The two issues are covered in separate subtasks and hidden behind a
> configuration parameter.
