Hue is not supported on Ubuntu or Debian. |
Complete the following prerequisites before deploying Hue.
Verify that you have a host that supports Hue:
64-bit Red Hat Enterprise Linux (RHEL) 5 or 6
64-bit CentOS 5 or 6• 64-bit Oracle Linux 5 or 6
64-bit SUSE Linux Enterprise Server (SLES) 11, SP1, SP3, and SP4
Verify that you have a browser that supports Hue:

Verify that you have at least Python 2.6.6 or higher installed.
Stop all of the services in your cluster. For more information see the instructions provided in the HDP Reference Guide.
Install and run the HDP Hadoop cluster from HDP-2.2.X.

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.
The Hive client configuration (hive-site.xml file) needs to be populated on the host to run Hue. In the beeswax section of hue.ini, configure hive_conf_dir to point to the location of the Hive configuration:
hive_conf_dir=/etc/hive/confConfigure 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.
