2. Meet Minimum System Requirements

To install and manage a Hadoop cluster using Ambari, your system must meet minimum requirements.

 2.1. Hardware Recommendations

 2.2. Operating Systems Requirements

The following operating systems are supported:

  • Red Hat Enterprise Linux (RHEL) v5.x or 6.x (64-bit)

  • CentOS v5.x or 6.x (64-bit)

  • SUSE Linux Enterprise Server (SLES) 11, SP1 (64-bit)

[Important]Important

The installer pulls many packages from the base OS repos. If you do not have a complete set of base OS repos available to all your machines at the time of installation you may run into issues.

For example, if you are using RHEL 6 your hosts must be able to access the "Red Hat Enterprise Linux Server 6 Optional (RPMs)" repo. If this repo is disabled, the installation is unable to access the rubygems package, which is necessary for Ambari to operate.

If you encounter problems with base OS repos being unavailable, please contact your system administrator to arrange for these additional repos to be proxied or mirrored. For more information see Optional: Configure the Local Repositories
