3.3. Use Manual Kerberos Setup
To perform Manual Kerberos Setup, you must prepare the following:
Cluster hosts have network access to the KDC.
Kerberos client utilities (such as kinit) have been installed on every cluster host.
The Java Cryptography Extensions (JCE) have been setup on the Ambari Server host and all hosts in the cluster.
The Service and Ambari Principals will be manually created in the KDC before completing this wizard.
The keytabs for the Service and Ambari Principals will be manually created and distributed to cluster hosts before completing this wizard.
Proceed with Enabling Kerberos Security in Ambari.
