1. Prerequisites

Complete the following prerequisites before deploying Hue.

	Note
Hue is not supported on Ubuntu.

Verify that you have a browser that supports Hue:

Table 13.1. Hue Browser Support

Linux (RHEL, CentOS, Oracle, SLES)	Windows (VISTA, 7)	Mac OS X (10.6 or later)
Firefox latest stable release	Firefox latest stable release	Firefox latest stable release
Google Chrome latest stable release	Google Chrome latest stable release	Google Chrome latest stable release
N/A	Internet Explorer 9 (for Vista + Windows 7)	N/A
N/A	Safari latest stable release	Safari latest stable release

For RHEL/CentOs/Oracle 5.x verify that you are deploying the following dependency on all the host machines in your cluster:
```
yum install python26
```
Stop all the services in your cluster. For more information see the instructions provided here.

Install and run the HDP Hadoop cluster from HDP-2.1.X.

The following table outlines the dependencies on the HDP components:

Table 13.2. Dependencies on the HDP components

Component	Required	Applications	Notes
HDFS	Yes	Core, Filebrowser	HDFS access through WebHDFS or HttpFS
YARN	Yes	JobDesigner, JobBrowser, Beeswax	Transitive dependency via Hive or Oozie
Oozie	No	JobDesigner, Oozie	Oozie access through REST API
Hive	No	Beeswax, HCatalog	Beeswax uses the Hive client libraries
WebHCat	No	HCatalog, Pig	HCatalog and Pig use WebHcat REST API
HBase	No	Shell	Optionally provides access to the HBase shell

Choose a Hue Server host machine in your cluster where you want to deploy your Hue Server.
Typically, you can choose to deploy Hue on any node within your cluster. However, if your corporate firewall policies allow, you can also use a remote host machine as your Hue server. For pilot or small cluster sizes, you can use the master install machine for HDP as your Hue server.
Configure the firewall.
1. Verify that the host machines within your cluster can connect to each other over TCP.
2. 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.
