Chengbing Liu commented on OOZIE-2204:
--------------------------------------
We have very similar cases where we use a script to decide whether the input
file is ready. It would be nice if we could support this.

> Reporter: nirav patel
>
> use case is our workflows depend on external system to tell us whether input
> data set is ready for processing or not and which location they will be at.
> It would be nice if I can call a custom trigger which evaluate these
> conditions and prepare workflow configuration before calling subsequent
> workflows on dataset.
