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.

If you are using JDK1.7 (which was deprecated in HDP 2.6.0), you will need to add a custom parameter (ranger.tomcat.ciphers) to your ranger configuration (`ranger-admin-site` and `ranger-kms-site`) before upgrading to HDP 2.6.1. This is applicable for fresh installs as well (only when using JDK 1.7). For more information, see Workaround for Ranger service check failure.
