My Flink job failed to checkpoint with a "The job has failed" error. The logs contained no other recent errors. I keep hitting the error even if I cancel the jobs and restart them. When I restarted my jobmanager and taskmanager, the error went away.
What error am I hitting? It looks like there is bad state that lives outside the scope of a job. How often do people restart their jobmanagers and taskmanager to deal with errors like this?
