HelloREEFNoClient behavior
Hi,
It's been a while since I tried out HelloREEFNoClient. What's the expected
behavior?
It does not finish after submitting a job.
I'm also curious who's using the client-less mode.
Thanks.

Odd. The client should exit right after it submits the Job, IIRC. We
might have introduced this new behavior in one of the recent changes.

The .NET code base uses it. There, communication between client and
driver is facilitated via HTTP.
Client-less mode is also handy whenever the client is not run on a
machine on the cluster. Our client breaks down on network changes, can't
traverse firewalls and doesn't suffer the standby mode of a laptop well.
In other words: I believe the majority of the non-development runs are
client-less.
