> 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.
