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.authenticationproperty to enable or disable Kerberos authentication. When the
hadoop.security.authenticationproperty is updated, the Ranger service gets a restart indicator for the
core-site.xmlfile that resides inside the Ranger service conf directory generated by Cloudera Manager.
Ranger Kerberos authentication is automatically enabled when HDFS Kerberos authentication is enabled.
