The Kerberos principal for HDFS is configured by default to use the same service
principal as the default process user. However, you can change the default setting by
providing a custom principal in Cloudera Manager.
-
Log in to Cloudera Manager as an Administrator.
-
Go to Clusters > HDFS service > Configuration and search
for the Kerberos Principal by entering "kerberos" in the search field.
-
Enter the custom Kerberos principal in the Kerberos
Principal field.
This Kerberos principal short name is used by all the roles of HDFS.
-
Click Save Changes and restart the HDFS service.
