Yang Wang commented on FLINK-28350: ----------------------------------- AFAIK, we changed the HA format in the release-1.15. BTW, I strongly do not recommend to use the last-state upgrade across Flink major version changes(e.g. 1.14 -> 1.15). This also means that we could always trigger the savepoint in this case. > Test last-state upgrades across Flink minor versions > ---------------------------------------------------- > > Key: FLINK-28350 > URL: https://issues.apache.org/jira/browse/FLINK-28350 > Project: Flink > Issue Type: Improvement > Components: Kubernetes Operator > Reporter: Gyula Fora > Assignee: Gyula Fora > Priority: Critical > Fix For: kubernetes-operator-1.1.0 > > > Since the operator relies on the HA metadata for last-state upgrades we > should make sure that it is possible to upgrade between Flink versions using > that. > In some cases due to the HA format changes it might not be possible, if so we > should force SAVEPOINT upgrade in those cases > cc [~wangyang0918] -- This message was sent by Atlassian Jira (v8.20.10#820010)
