[jira] [Updated] (FLINK-19401) Job stuck in restart loop due to
"Could not find registered job manager"
[ https://issues.apache.org/jira/browse/FLINK-19401?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.

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

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.
