Hi Desind,   Thanks for the quick reply and solution, my paths are different to the ones you describe so i did the following:   Stop Navigator   mv /var/lib/cloudera-scm-navigator /var/lib/cloudera-scm-navigator.bak   Start Navigator   The /var/lib/cloudera-scm-navigator was regnerated when Navigator was started but the following folfer was not regenerated: /var/lib/cloudera-scm-navigator/diagnosticData   The Navigator Metadata Server is working ok now but just wondered why this diagnosticData folder is missing.   Many Thanks, Chris ...
