-------------------------------------------
Summary: Flink JobManager failed to restart after failure in
kubernetes HA setup
Key: FLINK-22014
URL: https://issues.apache.org/jira/browse/FLINK-22014
Project: Flink
Issue Type: Bug
Components: Deployment / Kubernetes
Affects Versions: 1.12.2
Reporter: Mikalai Lushchytski
After the JobManager pod failed and the new one started, it was not able to
recover jobs due to the absence of recovery data in storage - config map
pointed at not existing file.
Due to this the JobManager pod entered into the `CrashLoopBackOff`state and was
not able to recover - each attempt failed with the same error so the whole
cluster became unrecoverable and not operating.
I had to manually delete the config map and start the jobs again without the
save point.
If I tried to emulate the failure further by deleting job manager pod manually,
the new pod every time recovered well and issue was not reproducible anymore
artificially.
Below is the failure log:
