HBase provides a web-based user interface that you can use to monitor your HBase cluster. When you run HBase on Amazon EMR, the web interface runs on the master node and can be viewed using port forwarding, also known as creating an SSH tunnel.
To view the HBase User Interface
Use SSH to tunnel into the master node and create a secure connection. For information on how to create an SSH tunnel to the master node, see Option 2, Part 1: Set Up an SSH Tunnel to the Master Node Using Dynamic Port Forwarding.
Install a web browser with a proxy tool, such as the FoxyProxy plug-in for Firefox, to create a SOCKS proxy for domains of the type *ec2*.amazonaws.com*. For a tutorial on how to do this, see Option 2, Part 2: Configure Proxy Settings to View Websites Hosted on the Master Node.
With the proxy set and the SSH connection open, you can view the HBase UI by opening a browser window with http://
master-public-dns-name is the public DNS address of the master server in the HBase cluster. For information on how to locate the public DNS name of a master node, see To retrieve the public DNS name of the
master node using the Amazon EMR console.
