Upgrading to HDP 2.5.6
If you already have HDP 2.5.0 installed, upgrading your cluster to HDP 2.5.6 means:
Keeping the same configuration files you used for HDP 2.5.0.
Keeping the same data and metadata in the same location you used for HDP 2.5.0
Installing any new components (added for the first time in HDP 2.5.0) side-by-side with existing components
Before you begin
Ensure that you know which HDP components you need to upgrade at your installation.
Decide whether you are going to upgrade using a local repository or a remote repository.
If you are using the Falcon service, install the Berkeley DB prior to performing an upgrade.
See the "Prerequisite to Installing or Upgrading Falcon" in the Data Movement and Integration guide.
Upgrade options
If you are upgrading your cluster manually, use the Non-Ambari Upgrade Guide.
