​Chapter 3. Upgrade from HDP 2.2 to HDP 2.5.5 Manually

This chapter provides instructions on how to manually upgrade to HDP 2.5.5 from the HDP 2.2 release. It assumes the existing HDP 2.2 was also installed manually.

[Important]Important

If you installed and manage HDP 2.2 with Ambari, you must use the Ambari Upgrade Guide to perform the the HDP 2.2 to HDP 2.5.5 upgrade.

These instructions cover the upgrade between two minor releases. If you need to upgrade between two maintenance releases, follow the upgrade instructions in the HDP Release Notes.

Rolling Upgrade involves complex orchestration as well as side-by-side installation. It is too complex for a manual procedure, and is therefore supported only as an Ambari feature. If you wish to perform a Rolling Upgrade, refer to the Ambari Install instructions to install Ambari, then follow the Ambari Rolling Upgrade instructions, see Ambari Upgrade Guide.

The HDP packages for a complete installation of HDP 2.5.5 consumes about 6.5 GB of disk space.

[Warning]Warning

Until the upgrade is finalized, no HDFS data is deleted from the cluster. Be sure to review your capacity and ensure that you have extra space available during the upgrade window.
