Subject Name node and data node replacement
Date Mon, 09 Dec 2013 11:52:44 GMT

I am trying to understand,how to recover a Name node or Data node failure
in case if those nodes are unable to come up due to unexpected issues.

Is there a way to replace Name node with new name node without loosing
data.I mean new Name node should have all the data from original Name node.
Similarly for Data node.
