Hi
Really sorry for keep posting. Next time, I will dig more before posting.
I finally got my session created after removing "livy.spark.master":
"yarn-cluster". Does "yarn" mean yarn client mode? Does that mean livy
server should run driver in yarn-client mode? I imagine the client (which
is livy) will not go away so yarn-client mode is OK? But why "yarn-cluster"
is not working?
Sorry I am a newbie to spark.
