Subject Re: When using spark shell, classpath on workers does not seem to see all of my custom classes
Date Mon, 09 Sep 2013 17:27:34 GMT
That resolves the issue.  What is strange to me is that with just the
'ADD_JARS' set, before the map is called I am able to import my main
package object and use functions defined in that jar.  The failure is when
the mapper function starts to run.
