Use this procedure for upgrading from HDP 2.2 to HDP 2.3. This procedure will require cluster downtime. You are strongly encouraged to read completely through this entire document before starting the upgrade process, to that you understand the interdependencies and order of the steps. It is highly recommended you validate these steps in a test environment to adjust + account for any special configurations for your cluster.
The high-level process for performing an HDP 2.2 -> 2.3 Manual Upgrade is as follows:
Prior to upgrading to HDP 2.3, you must first upgrade to Ambari 2.1. Make sure Ambari is upgraded and the cluster is healthy and operating normally prior to attempting to upgrade from HDP 2.2 to HDP 2.3. See Upgrading Ambari for more information on performing the Ambari upgrade. Once you are running Ambari 2.1, follow these steps to upgrade the Stack from HDP 2.2 to HDP 2.3.
