             Summary: parameterize coord EL functions (latest and current)
                 Key: OOZIE-1504
                 URL: https://issues.apache.org/jira/browse/OOZIE-1504
             Project: Oozie
          Issue Type: Bug
    Affects Versions: trunk
            Reporter: Ryota Egashira


for example, coordinator.xml
-----
    <input-events>
         <data-in name="foo" dataset="bar">
            <start-instance>${coord:latest(-365)}</start-instance>
            <end-instance>${coord:latest(0)}</end-instance>
         </data-in>
    </input-events>
-----
there are use cases to use the same coordinator.xml for varying number of data instances (not always 365). but the parameter to coord EL function cannot be parametrized (by using job
config), customer needs to copy coordinator.xml with different number just to change the parameter of coord:latest(), which is not optimal for maintenance.
