Interpreters not found

[Rahul Palamuttam]

Hi everyone,

I am new on the mailing list.
I'm running zeppelin and attempting to launch jobs to my spark cluster.
(Both master and zeppelin are on the same machine).

However I keep getting the following interpreters not found error :

ERROR [2015-07-30 08:44:33,245] ({pool-1-thread-2}

When I attempt to restart the interpreter and run the tutorial, I get
scheduler already terminated error.

Thanks,
