Any changes to the Hue service before users noticed the issue?    Ans- Yes,it was working before.No changes.   2) Is this issue happening to single user or multiple users?   Ans- Yes to every users.   3) Have you tried to use different machine/browser to log in and see if this issue resides on server side or client side.   Ans- Different machine means you want to install HUE service in another machine ?

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.
