  6. Choose a Hue Server host machine in your cluster to deploy your Hue Server.

    You can deploy Hue on any host within your cluster. If your corporate firewall policies allow, you can also use a remote host machine as your Hue server. For evaluation or small cluster sizes, use the master install machine for HDP as your Hue server.

  7. Configure the firewall.

    • Verify that the host machines within your cluster can connect to each other over TCP.

    • The machines outside your cluster must be able to open TCP port 8000 on the Hue Server (or the configured Hue web HTTP port) to interact with the system.
