> Today the source table's cardinality calculation is a synced action which need be taken by the admin; The action will trigger a map-reduce job and blocks the user's action. If the hive table is small that is okay, but if it is a big table, the job may take tens of minutes to finish, that is not user friendly.
> With the generic job flow engine be released, the cardinality calculation should be able to converted to a backend job, so user doesn't need be hold on UI.
