Subject Re: Non-interactive job fails to copy local variable to remote machines
Date Wed, 29 Jan 2014 22:54:37 GMT
Could you give some more details? e.g. the context of your code and the
exception stack trace.

Your code seems weired, do you have already new a SparkContext ? REPL will
add some necessary components while application would not.
