Your failure seems to be in the task-side. I suspect a mix of libraries.
What version of Hadoop are you *deploying* across all nodes?

I packaged your code from the below link and am able to run it just
fine on 1.0.3. and a bunch of other versions I have on my machine.
Could you share your specific error please?

The answer there is bogus. There is no such issue that makes you not
use mapred.* API over mapreduce.*. The problem was something else that
should've taken some more debugging to find out, but the asker now
believes it was the use of the stable API.
