Installing the Ranger Key Management Service

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 “Installing Ranger Using Ambari”. (For more information about the Ambari Add Service Wizard, see “Apache Ambari Operations > Adding a Service” in Apache Ambari Operations.)

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 for Kerberos”. Make sure that the Java location is specified in the $PATH environment variable.
