Dear all,
I had to change the IP address of a hbase region server in the cluster. After
effecting the IP change, all services in cluster came up fine, but for the
region server on this node.
Kindly advise how to solve this problem.
The log on the region server with the error portion is as below:
2013-11-08 13:41:13,780 DEBUG
