Hello,
our Hortonworks cluster is stuck on scaling for last 24 hours and I can't seem to do anything. I tried restarting ambari on master and also the EC2 instance, but its still stuck there. My last action on the HDP Data Cloud UI to increase its size by 2 more nodes caused this, I can't seem to undo or fix this. AWS console shows the 2 new instances requested from HDP UI are not setup, not sure why HDP is stuck.
Help will be appreciated.
The state of one or more instances couldn't be determined. Try syncing later. [this is the only information repeating on HDP Cloud UI]
