Hi,
I have two virtual pcs on private cloud (ubuntu 14). I installed spark
2.0 preview on both machines. I then tried to test it with standalone mode.
I have no problem start the master. However, when I start the worker
(slave) on another machine, it makes many attempts to connect to master and
failed at the end.
I can ssh from each machine to another without any problem. I can also
run a master and worker at the same machine without any problem.
What did I miss? Any clue?
here are the messages:
WARN NativeCodeLoader: Unable to load native-hadoop library for your
platform ... using builtin-java classes where applicable

INFO Worker: Connecting to master ip:7077 ...

Thanks,
