----------------------------------
Summary: Improve manual savepoint tracking
Key: FLINK-27675
URL: https://issues.apache.org/jira/browse/FLINK-27675
Project: Flink
Issue Type: Improvement
Components: Kubernetes Operator
Reporter: Gyula Fora
Fix For: kubernetes-operator-1.0.0
There are 2 problems with the manual savpeoint result observing logic that can
cause the reconciler to not make progress with the deployment (recoveries,
upgrades etc).
# Whenever the jobmanager deployment is not in READY state or the job itself
is not RUNNING, the trigger info must be reset and we should not try to query
it anymore. Flink will not retry the savepoint if the job fails, restarted
anyways.
# If there is a sensible error when fetching the savepoint status (such as:
There is no savepoint operation with triggerId=xxx for job ) we should simply
reset the trigger. These errors will never go away on their own and will simply
cause the deployment to get stuck in observing/waiting for a savepoint to
complete
