Hardware Recommendations:
Although there is no single hardware requirement for installing HDP, there are some basic guidelines. You can see sample setups here.
Operating Systems Requirements:
The following operating systems are supported:
64-bit Red Hat Enterprise Linux (RHEL) v5.*, v6.*
64-bit CentOS v5.*, v6.*
64-bit SUSE Linux Enterprise Server (SLES) 11 SP1
Software Requirements:
On each of your hosts:
yum
rpm
scp
curl
wget
pdsh
Database Requirements:
Hive and HCatalog require a database to use as a metadata store. MySQL 5.x or Oracle 11gr2 are supported. You may provide access to an existing database, or the Ambari and gsInstaller installers will install MySQL for you if you want.
Oozie requires a database to use as a metadata store, but comes with embedded Derby database by default. MySQL 5.x or Oracle 11gr2 are also supported.
Ambari requires a database to use as a metadata store, but comes with Postgres 8.x. This is the only database supported in this version.
Optional: Configure the local repositories
If your cluster does not have access to the Internet, or you are creating a large cluster and you want to conserve bandwidth, you need to provide access to the HDP installation packages using an alternative method. For more information, see Deploying HDP In Production Data Centers.

The installer pulls many packages from the base OS repositories.
If you do not have a complete base OS 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)” repository.
If this repository is disabled, the installation is unable to access the |

gsInstaller is deprecated as of HDP 1.2.1 and will not be made available in future minor and major releases of HDP. We encourage you to consider Manual Install (RPMs) or Automated Install (Ambari). |
