This section describes how to install the Ranger Key Management Service (KMS) using Ambari on a Kerberized cluster.

Prerequisites

Ranger KMS requires HDFS and Ranger to be installed and running on the cluster.

To install Ranger using Ambari, refer to the Ranger Installation Guide. (For more information about the Ambari Add Service Wizard, see Adding a Service in the Ambari User's Guide.)

To use 256-bit keys, install the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy File on all hosts in the cluster. For installation information, see Install the JCE. Make sure that the Java location is specified in the $PATH environment variable.

	Note
	If you use the OpenJDK package, the JCE file is already built into the package.
