> There is a split brain problem in
> org.apache.falcon.converter.OozieProcessMapper. The inputs use '#' as a
> separator but outputs use ',' as a separator for feed names and instance
> paths.
> org.apache.falcon.converter.OozieProcessMapper#initializeInputPaths
> {code}
> props.put("falconInputFeeds", join(inputFeeds.iterator(), '#'));
> props.put("falconInPaths", join(inputPaths.iterator(), '#'));
> {code}
> org.apache.falcon.converter.OozieProcessMapper#initializeOutputPaths
> {code}
> // Output feed name and path for parent workflow
> props.put(ARG.feedNames.getPropName(), join(outputFeeds.iterator(),
> ','));
> props.put(ARG.feedInstancePaths.getPropName(),
> join(outputPaths.iterator(), ','));
> {code}
