Ambari 2.0 has the capability to perform an automated cluster upgrade for maintenance and patch releases for the Stack. This capability is available for HDP 2.2 Stack only. If you have a cluster running HDP 2.2, you can perform Stack upgrades to later maintenance and patch releases. For example: you can upgrade from the GA release of HDP 2.2 (which is HDP 2.2.0.0) to the first maintenance release of HDP 2.2 (which is HDP 2.2.4.2).
This section describes the steps to perform an upgrade from HDP 2.2.0 to HDP 2.2.4.
