Kerberos authentication error during scan

When a scan fails immediately with Kerberos authentication errors, verify Kerberos is enabled on the CMA Agent and the keytab is valid.

Symptom: Scan fails immediately with authentication errors in the CMA Agent log.

  1. Verify that kerberos.auth.enable is set to true in the CMA Agent service configuration in Cloudera Manager.
  2. Verify that the keytab file is valid. 
    klist -kt /path/to/keytab
  3. Retry the scan.
