We did not put it on maintenance mode.Just added without stopping any services.. Now the result is we are unable to start that data node.It came up for a while and than went down. We have restarted Namenode , check the configuration directory , re balance it.. NO LUCK. We are unable to make it up. But the region server on that particular node is running fine.
