----------------------------------
Summary: Do not observe cluster/job mid upgrade
Key: FLINK-27804
URL: https://issues.apache.org/jira/browse/FLINK-27804
Project: Flink
Issue Type: Improvement
Components: Kubernetes Operator
Affects Versions: kubernetes-operator-1.0.0
Reporter: Gyula Fora
Assignee: Gyula Fora
Seems like in some weird cornercases when we observe the FINISHED job (stopped
with savepoint) during an upgrade the recorded last snapshot is incorrect
(still need to investigate if this is due to a Flink problem or what) This can
lead to upgrade errors.
This can be avoided by simply skipping the observe step when the reconciliation
status is UPGRADING because at that point we actually know that the job was
already shut down and state recorded correctly in the savepoint info.
