Grab a copy of the maintainance guide: htt= p://shop.oreilly.com/product/0636920025085.do?sortby=3DpublicationDate<= br>

Dear All,

I have just restarted machines of my hadoop clusters. Now, I am trying to= restart hadoop clusters again, but getting error on namenode restart. I am= afraid of loosing my data as it was properly running for more than 3 month= s. Currently, I believe if I do namenode formatting, it will work again, ho= wever, data will be lost.

I will really appreciate any help.
