Hi Arun/Vinod,

After commit d4dca4eabf83a97d158f1e1caa4801020679d5e2
Date:   Wed Sep 21 18:52:27 2011 +0000
MAPREDUCE-2880. svn merge -c r1173783 --ignore-ancestry ../../trunk/
git-svn-id:
https://svn.apache.org/repos/asf/hadoop/common/branches/branch-0.23@117379213f79535-47bb-0310-9956-ffa450edef68

My mapreduce jobs are failing
2011-09-23 10:27:08,534 INFO  ipc.HadoopYarnRPC

Digging into the stderr logs: I see this single line
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/hadoop/mapreduce/v2/app/MRAppMaster

What do I need to add to my environment / config so that the magic happens
again?

Thanks
Ravi.
