Did you first create FlinkCluster with spec.job.savepointsDir empty and then update spec.job.savepointsDir?
As of now, FlinkCluster spec update is only allowed if spec.job.savepointsDir is initially set.

I think I don't change spec.job.savepointsDir. It this related #392 I rebuild the operator and do it again. It is fine now.
