Step 3: Check out the Unravel UI with your EMR cluster connected
Once the cluster is created, and you go back to the Unravel UI (http://), within a few seconds, you should see the cluster ID in the main dashboard dropdown on the right and some data in various charts.hostname-or-ip-address-of-the-instance:3000
You can now run applications in your cluster and use Unravel to optimize them. Applications you run will show up in the Applications tab.
For details on using Unravel UI, see User guide.
