@Prakash Punj Are you expecting to see number of active users in cluster or Currently logged in users ? if you are looking to find total active users. yes, we can find in Ambari-> Admin-> Manage Ambari-> Users -> Active if you are looking to find currently logged in user. I don't think we have such functionality in Ambari Dashboard

you need to consider "Configuration for Master-Master-Active-Passive" link we are running two Ambari-servers in my project and pointing to same DB. If one DB does down we can make few changes in ambari conf to point another host HA datatabase. As per my knowledge there is no Ambari-server HA in Hortonworks..we have to do this through any database while implementing database HA.

@Ram D I think you can consider this. 1) create AmbariDB HA on new client host (non-ec2) 2) install ambari-server on new host and point ambaridb it to ec2 (Primary) if Ec2 goes down 1) make non-ec2 ambari-server as primary while making few changes in Ambari config like pointing new db.

Is multiple disks on the same node? if yes, I think you can decommission the node from Ambari->hosts->data node -> you will find decommission from drop down.
