Subject reducer not "seeing" external jars
Date Mon, 30 Apr 2012 20:46:44 GMT
I'm trying to use -libjars to load an external jar along with the job jar, but the reducer
still fails with a ClassNotFoundException against a class from the external jar (JFreeChart).
 I'm not really sure how to approach this.  It either works or it doesn't...and so far it
doesn't.

Can I make the mapper or reducer dump the class path so I can see what it thinks it has access
to?

Aside from exploring the issue, like investigating the classpath, etc., why might -libjars
not work as expected in the first place?

Thanks.
