Yang Wang commented on FLINK-27095:
-----------------------------------
I second [~gyfora]'s comments. If the user want to change an application
cluster to session, they not only need to remove the {{.spec.job}} field, but
also need to create a new {{FlinkSessionJob}} CR. So I think deleting the old
{{FlinkDeloyment}} does not take too much burden.
> Allow FlinkDeployment Mode Switching
> ------------------------------------
>
> Key: FLINK-27095
> URL: https://issues.apache.org/jira/browse/FLINK-27095
> Project: Flink
> Issue Type: Improvement
> Components: Kubernetes Operator
> Reporter: Usamah Jassat
> Priority: Major
>
> Currently the operator doesn't allow switching the mode of an existing
> FlinkDeployment between Application and Session.
> I don't see why this shouldn't be allowed, if the mode is switched we should
> tear-down the cluster and spin-up a new cluster running in this new mode. It
> will add complexity into the connector but seems like a valid use-case.
