Team,

I am getting this issue when reducer starts executing after map's
completed. After job failed with below exception when i restart its running
fine.
We are getting this issue after upgrading to MRv1(CDH4).

Any inputs will be more helpful, Thanks in advance.

Hi Manoj,

It's related to your JVM. Which version are you using?
