Before you can upgrade the Apache Ranger service, you must have first upgraded your HDP components to the latest version (in this case, 2.4.0). This section assumes that you already have already performed the following tasks, however, if you have not already performed these steps, refer to the "Upgrade HDP 2.1 Components" section in this guide for instructions on how to upgrade your HDP components to 2.4.0.

	Note
	XA Secure was an add-on component in HDP-2.1. Ranger is the new name for XA Secure. In HDP-2.2 and subsequent releases, Ranger is installed with HDP.
