UI Behavior for Non-Kerberized Clusters

For a secure cluster with Kerberos enabled, the Hadoop Authentication tab displays a Kerberos section with fields to enter your Kerberos principal and username. However, if Cloudera Data Science Workbench cannot detect a krb5.conf file on the host, it will assume the cluster is not kerberized, and the Hadoop Authentication tab will display Hadoop Username Override configuration instead.

For a non-kerberized cluster, by default, your Hadoop username will be set to your Cloudera Data Science Workbench username. To override this default and set an alternative HADOOP_USER_NAME, go to the Hadoop Username Override setting at Account settings > Hadoop Authentication.

If the Hadoop Authentication tab is incorrectly displaying Kerberos configuration fields for a non-kerberized cluster, make sure the krb5.conf file is not present on the host running Cloudera Data Science Workbench. If you do find any instances of krb5.conf on the host, depending on your deployment, perform one of the following sets of actions:

• On CSD deployments, go to Cloudera Manager and stop the CDSW service. Remove the krb5.conf file(s) from the Cloudera Data Science Workbench gateway host, and then start the CDSW in Cloudera Manager.

  OR

• On RPM deployments, run cdsw stop, remove the krb5.conf file(s) from the Cloudera Data Science Workbench gateway host, and run cdsw start.

You should now see the expected Hadoop Username Override configuration field.
