Configure Kerberos authentication for Apache Ranger

How to configure Kerberos Authentication for Apache Ranger

Kerberos authentication for Apache Ranger is automatically configured when HDFS Kerberos authentication is configured in Cloudera Manager (typically using the Cloudera Manager Kerberos Wizard). In this way, the actions that Ranger authorizes are sure to be requested by authenticated users.

Specifically, Ranger depends on the HDFS hadoop.security.authentication property to enable or disable Kerberos authentication. When the hadoop.security.authentication property is updated, the Ranger service gets a restart indicator for the core-site.xml file that resides inside the Ranger service conf directory generated by Cloudera Manager.

Ranger Kerberos authentication is automatically enabled when HDFS Kerberos authentication is enabled.
