If the cluster your views will communicate with is Kerberos-enabled, you need to configure the Ambari Server instance(s) for Kerberos and be sure to configure the views to work with Kerberos.

Refer to the Set Up Kerberos for Ambari for the instructions on how to configure Ambari Server for Kerberos. Be sure to configure all standalone Ambari Server instances for Kerberos.

	Important
	Be sure to install the Kerberos client utilities on the Ambari Server so that Ambari can kinit. RHEL/CentOS/Oracle Linux yum install krb5-workstation SLES zypper install krb5-client Ubuntu/Debian apt-get install krb5-user krb5-config

Once your Ambari Server is setup for Kerberos, be sure to follow the specific instructions with each view on how to configure the view for Kerberos and the cluster for Kerberos access from the view. Also, if the view requires HDFS or WebHCat to be configured for a proxy user, instead of using the ambari-server daemon user as the proxy user, you must user primary Kerberos principal. For example, if you configure Ambari Server for Kerberos principal ambari-server@EXAMPLE.COM, this value would be ambari-server.
