Hue is using a database for persisting all its states, user information, documents of users like Hive Queries, workflows, Pig script... etc If the Hue service crashes before you click save, you will have to have it back up in order to save the document (think like gmail without the auto save if you un-plug your computer, but https://issues.cloudera.org/browse/HUE-2669 is targeting that). http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/cdh_ig_hue_database.html http://gethue.com/how-to-manage-the-hue-database-with-the-shell/ The new Oozie Editor makes it easier to export workflows from the Hue DB in the Hue format: http://gethue.com/export-and-import-your-oozie-workflows/ In Hue 4, workflows will be exportable/importable in the Hue format + XML directly from the UI.
