Steven Zhen Wu updated FLINK-19401: ----------------------------------- 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. {code} 2020-09-19 00:03:31,614 INFO
