Chapter 3. Upgrade from HDP 1.3 to HDP 2.2 Manually

HDP 2.2 supports side-by-side installation of HDP 2.2 and above releases, which lets you perform rolling upgrades on your cluster and improve execution times for in-place upgrade. To support side-by-side installation, the HDP package version naming convention for both RPMs and Debs has changed to include the HDP 2.2 product version. For example, hadoop-hdfs is now hadoop-2.2.6.0-hdfs. HDP 2.2 marks the first release where HDP rpms, debs, and directories contain versions in the names to permit side-by-side installations of later HDP releases.

To select from the releases you have installed side-by-side, Hortonworks provides hdp-select, a command that lets you select the active version of HDP from the versions you have selected.

The HDP packages for a complete installation of HDP 2.2 will take about 2.5 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.
