Although you could use different Start time to kick off different coordinator applications, it is hard to provide a good estimate of the Start times, especially when you have many independent workflows to run (with the same frequency, like daily or weekly). Does it make sense to relax the current coordinator/bundle schema to allow
[1] multiple workflows in the action of a coordinator application, OR [2] multiple actions in a coordinator application, OR [3] floating Start time of a coordinator job inside a bundle where the coordinator application will start when the previous one ends?

What can be done is, using different Start and End times for your different coordinators in order to stagger them. Please see the example referred here for parametrizing start times. http://oozie.apache.org/docs/3.2.0-incubating/BundleFunctionalSpec.html#a3. _Expression_Language_for_Parameterization -- Mona Chitnis On 11/19/12 10:42 AM, "Yongcheng Li" <[email protected]> wrote: >Is it possible to have two coordinator apps run one after another, i.e. >the second one starts after the first one ends?
