> When TaskManager register to JobManager, JM will send a "NotifyResourceStarted" message to kick off Resource Manager, then trigger a reconnection to resource manager through sending a "TriggerRegistrationAtJobManager".
> When the ref of resource manager in JobManager is not None and the reconnection is to same resource manager, JobManager will go to a infinite message sending loop which will always sending himself a "ReconnectResourceManager" every 2 seconds.
> We have already observed that phonomenon. More details, check how JobManager handles `ReconnectResourceManager`.
