> Key: OOZIE-1504
> URL: https://issues.apache.org/jira/browse/OOZIE-1504
> Project: Oozie
> Issue Type: Improvement
> Affects Versions: trunk
> Reporter: Ryota Egashira
> Assignee: purshotam shah
> Fix For: trunk
>
> Attachments: OOZIE-1504_v4.patch

>
> 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.
