Hi Manisha,

I think you hadoop cluster is in safemode. To quit safemode, please run the following command :

$ hadoop dfsadmin -safemode leave

This will resolve the issue.

Hope this helps. Please let me know if you any doubts.

Thanks.

Hi Manisha,

I had the same problem. I hope you have better luck than I did.  Still have not found a solution.

Manisha - Try using the comman below in both name and data nodes.

$ hadoop dfsadmin -safemode leave

Good luck.
