NOTE: In the examples that follow, user details, cluster names, hostnames, directory paths, filenames, etc. represent a fictitious sample (and are used to provide an illustrative example only).

The symptom is that Backup - Snapshot and File Browser are not loading in Cloudera Manager.  This happens on clusters which are Kerberos enabled.
