Subject running job without jar
Date Tue, 26 Oct 2010 07:01:13 GMT

When launching a job in hadoop, usually we use "hadoop jar xxx.jar input output".
Can I run a job simply by a java program (In fully distributed mode), without packing a jar.
I know this will cause problems because the remote nodes don't have the source code and .class
to run the mapper/reducer. So my next question is how to tell hadoop to copy user specified
files to different nodes?
