Hi,
Interpreter null not found.
This error is happening when there're no binded interpreter to your
notebook. You can bind interpreters with small gear button on top right
corner of your notebook.
ERROR [2015-07-13 16:56:11,020]
({sparkDriver-akka.actor.default-dispatcher-3}
Slf4jLogger.scala[apply$mcV$sp]:66) - Uncaught fatal error from thread
[sparkDriver-akka.remote.default-remote-dispatcher-5] shutting down
ActorSystem [sparkDriver]
java.lang.VerifyError: (class:
org/jboss/netty/channel/socket/nio/NioWorkerPool, method: createWorker
signature:
(Ljava/util/concurrent/Executor;)Lorg/jboss/netty/channel/socket/nio/AbstractNioWorker;)
Wrong return type in function
This error came from different reason. The problem can happen when you have
multiple version of the same library (netty) in your classpath.
Hope this helps.
Best,
moon
