Description

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

        props.put("falconInputFeeds", join(inputFeeds.iterator(), '#'));
        props.put("falconInPaths", join(inputPaths.iterator(), '#'));

org.apache.falcon.converter.OozieProcessMapper#initializeOutputPaths

        // Output feed name and path for parent workflow
        props.put(ARG.feedNames.getPropName(), join(outputFeeds.iterator(), ','));
        props.put(ARG.feedInstancePaths.getPropName(), join(outputPaths.iterator(), ','));
