--------------------------------------

Hi [~sihuazhou], thanks for taking care of this issue.

No, I don't think we should fail a job immediately when there are not enough resources. With the dynamic resource allocation feature of Flink 1.5, TMs can be spawned and register to the JM after a job was submitted. This does not work for stand-alone clusters which do not leverage a resource manager (YARN, Mesos, Kubernetes).

However, a job waiting for resources should not be displayed as running because it is not running yet (or will never be able to run in case of a stand-alone setup).

I don't know what would be the best solution for this issue. However, we should avoid changing the lifecycle states of a job.
