Attila Sasvari commented on OOZIE-2941:
---------------------------------------
[~Dongying Jiao] I re-tested the mapreduce example in my local environment, and
the workflow successfully finished. Before running the MR workflow, you should
first install Oozie sharelib and make sure jhs is running. As per your previous
commend, I suspect sharelib was not installed in your case. So I believe this
issue is not the same as my experience with the shell action example.
