Chapter 1. Overview

This document describes how to upgrade from HDP 2.2.0 to HDP 2.2.6 manually, using the HDP rolling upgrade feature. Rolling upgrade is supported on RHEL/CentOS/Oracle, SLES, Ubuntu, and Debian. If you have not yet upgraded to HDP 2.2, you will need to upgrade to HDP 2.2 before using the rolling upgrade feature.

If you use Ambari, see Automated HDP Stack Upgrade: HDP 2.2.0 to 2.2.x in the Ambari Documentation Suite.

If you would like to add new components to your cluster, complete the upgrade process first, and then install the new components.
