Kerberos
Prior to installing Kerberos on Cloudera Manager, you must collect the details from the Kerberos installation in Ambari.
Collect the values for the following settings:
KDC Type (AD, MIT KDC, Redhat IPA)
Admin Account Username
Admin Account Password
Kerberos Domain
Kerberos Realm
KDC Host
KDC Admin Host
Service Port (if non standard)
Encryption Type (default ‘rc4-hmac’)
AD Directory Suffix
Cloudera Manager maintains a single principal for all the roles in a service. Hence Auth_to_local rules are not migrated.
Service user names in Ambari will be migrated to Kerberos principal names in Cloudera manager as part of the transition process.
