Description

Flink job sometimes got into a restart loop for many hours and can't recover until redeployed. We had some issue with Kafka that initially caused the job to restart.

Below is the first of the many exceptions for "ResourceManagerException: Could not find registered job manager" error.

Grepped through our log. job manager registration happened once when the job was deployed a few days ago.

2020-09-16 17:23:28,081 INFO  com.netflix.spaas.runtime.resourcemanager.TitusResourceManager [flink-akka.actor.default-dispatcher-60]  - Registered job manager [e-mail]://flink@100.118.253.133:43917/user/jobmanager_0 for job 70216adbeed914b35d77717c4b7b13ea.

Then there were a flurry of 9 registrations in the same milli-seconds that happened ~30 mins after the first error of " Could not find registered job manager". The issue persisted many hours after this. Because this is a pre-prod job, so we didn't have alert on it.

I have the job manager logs for the hour with INFO level that I can share offline if needed.
