​Chapter 2. Upgrading to HDP 2.6.5

If you already have HDP 2.6.0 installed, upgrading your cluster to HDP 2.6.5 means:

  • Keeping the same configuration files you used for HDP 2.6.0.

  • Keeping the same data and metadata in the same location you used for HDP 2.6.0

  • Installing any new components (added for the first time in HDP 2.6.0) side-by-side with existing components
