Subject Re: Is there any way to add jar when invoking hadoop command
Date Wed, 23 Mar 2011 01:41:13 GMT
Hello, some quick advice for you....


which portion of your job needs the jar?  if answer = mapper or reducer, then add it to the
-libjars flag.

If it is in the job initiation..bundle it in your job jar for fun.

Cheers
James.
