Kerberos must be installed and configured on both PowerScale and Cloudera Manager. This process is different from the standard Cloudera process for enabling Kerberos since Kerberos must be enabled before deploying CDP Base.
First, enable Kerberos on the PowerScale cluster by following the instructions in the PowerScale CDP private base Install guide section 3.2.3, Enable Kerberos on the HDFS Zone and view HDFS settings.
Then enable Kerberos on Cloudera Manager. See Install Cloudera Manager and CDP for more details about enabling Kerberos on CDP 7.1.6 and the PowerScale CDP private base Install guide section 4.5, Kerberizing Cloudera Manager for more information.
