Subject Job Error:Actor not found for: ActorSelection[Anchor(akka.tcp://sparkDriver@130.1.10.108:23600/)
Date Fri, 25 Dec 2015 06:26:43 GMT
Hi,folks


I wrote some spark jobs and these jobs could ran successfully when I ran them one by one.
But if I ran them concurrently, for example 12 jobs parallel running, I met the following
error. Could anybody tell me what cause this? How to solve it? Many Thanks!
