             Summary: Lineage recording fails with NPE for processes with >1 inputs
                 Key: FALCON-360
                 URL: https://issues.apache.org/jira/browse/FALCON-360
             Project: Falcon
          Issue Type: Sub-task
    Affects Versions: 0.5
            Reporter: Venkatesh Seetharam


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}
