---------------------------------
Summary: Terminate jobmanager process with zero exit code to avoid
unexpected restarting by K8s
Key: FLINK-18828
URL: https://issues.apache.org/jira/browse/FLINK-18828
Project: Flink
Issue Type: Improvement
Components: Runtime / Coordination
Affects Versions: 1.11.1, 1.10.1, 1.12.0
Reporter: Yang Wang
Fix For: 1.10.2, 1.12.0, 1.11.2
Currently, Flink jobmanager process terminates with a non-zero exit code if the
job reaches the {{ApplicationStatus.FAILED}}. It is not ideal in K8s
deployment, since non-zero exit code will cause unexpected restarting. Also
from a framework's perspective, a FAILED job does not mean that Flink has
failed and, hence, the return code could still be 0.
> Note:
This is a special case for standalone K8s deployment. For
standalone/Yarn/Mesos/native K8s, terminating with non-zero exit code is
harmless. And a non-zero exit code could help to check the job result quickly.
