Earlier today I tried to add a new host to my Ambari-managed cluster. I managed to mess a few things up, and neither the DataNode nor the JobTracker could install properly. Deciding I needed to wipe the node and start over, I did so. I’m working on Amazon EC2, so my old IP address is long gone by now.
My problem is that I cannot get the Add New Host wizard to get UNSTUCK from the old install. It’s on the Install, Start and Test screen and won’t allow me to click Next, and there’s no back button! I even tried rebooting the entire cluster to get it unstuck, but when it comes back up it puts me back to this screen. Does anybody know how to get past this? Please help, I really don’t want to have to scrap the cluster and install from scratch because of this.
