Getting a 401 - Unauthorized access error message while accessing DAS

You get an “Unauthorized access” error when you click Data Analytics Studio UI from Ambari > Data Analytics Studio > Quick Links. This can happen in case your cluster is secured with Knox proxy.

To fix this issue, you must replace the contents of the quicklink.json file which is present in the /var/lib/ambari-server/resources/mpacks/data-analytics-studio-mpack-<VERSION>/hdp-addon-services/DATA_ANALYTICS_STUDIO/<VERSION>/quicklinks/ directory with the template provided in Setting up quick links for the DAS UI.
