dhruba borthakur updated HDFS-976:
----------------------------------

    Attachment: AvatarNode.patch
                AvatarNodeDescription.txt

A short writeup and code to implement a Hot failover for NameNode in hadoop 0.20. This code
is by no means complete and extensive  testing is required before it can be deployed. It is
developed purely as a contrib module so that the HA functionality is completely separated
from the existing NameNode.
