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 HDFShadoop.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.
