> {{JobManagerDeploymentStatus.READY}} does not mean the Flink cluster is ready
> for accepting REST API calls. This will cause problems when we are running
> session cluster.
> For example, if something is wrong or very slow with the leader election,
> {{JobManagerDeploymentStatus}} is {{READY}} but the session cluster is not
> ready for accepting job submission. What I mean is to update the
> {{JobManagerDeploymentStatus}} to {{READY}} only when the flink cluster is
> actually working.
> Another case is even though JobManager crashed backoff, the
> {{JobManagerDeploymentStatus}} is still {{READY}}.
