Upgrading to HDP 3.1.0

You must use Ambari to either do a major (HDP 2.6.x to HDP 3.1.0) or a minor (HDP 3.0.x to HDP 3.1.0) upgrade.

If you already have HDP 2.6.x or HDP 3.0.x installed, upgrading your cluster to HDP 3.1.0 means:

  • Keeping the same configuration files you used for HDP 2.6.x or HDP 3.0.x.
  • Keeping the same data and metadata in the same location you used for HDP 2.6.x or HDP 3.0.x.
  • Installing any new components (added for the first time in HDP 2.6.x or HDP 3.0.x) side-by-side with existing components.

Before you begin

  • Ensure that you know whether you want to do a major or a minor upgrade.
  • Ensure that you know which HDP components you need to upgrade at your installation.
  • Read the Prepare to Upgrade section in the Ambari Upgrade Guide.
  • See the Ambari Upgrade Guide for upgrade information and instructions.
