> A stateful job with stateless upgrade mode (yes, there are such use cases)
> fails with checkpoint path conflict due to constant jobId and FLINK-19358
> (applies to Flink < 1.16x). Since with stateless upgrade mode the checkpoint
> id resets on restart the job is going to write to previously used locations
> and fail. The workaround is to rotate the jobId on every redeploy when the
> upgrade mode is stateless. While this can be worked around externally it is
> best done in the operator itself because reconciliation resolves when a
> restart is actually required while rotating jobId externally may trigger
> unnecessary restarts.
