[Openstack] [Sahara] Jobs get marked as "failed" immediately on Spark cluster

Hello.

I haven't saw issues like that. Can you explain more precisely how you are
running job, what configs and arguments are passed, job binaries, and so
on. Minimal example for reproducing this issue should be a best option.

Moreover, this looks like a absolutely strange issue (if job was executed
successfully). It means that launching command was successful (see [0]).
But there is no copy operations after launching command.
