[jira] [Created] (FLINK-40553) Corrupted job-local HA data causes cluster-wide failover

Matthias Pohl created FLINK-40553:
-------------------------------------

             Summary: 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: 2.2.1, 2.3.0, 2.4.0
            Reporter: Matthias Pohl


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.
