Hue is taking advantage of a new way to specify the frequency of a coordinator in Oozie (OOZIE-1306). Here is how to put it in practice:

  {{< youtube Nnzd_q6vSHU >}} The crontab requires Oozie 4. In order to use the previous Frequency drop-down from Oozie 3, the feature can be disabled in [hue.ini][1]:  
[oozie]

 # Use Cron format for defining the frequency of a Coordinator instead of the old frequency number/unit.

 enable_cron_scheduling=false
