Rohini Palaniswamy commented on OOZIE-2787:
-------------------------------------------

Moving it to a JarFilter class is nice and code is more cleaner. Just need two 
more minor changes.

private class JarFilter -> private static class JarFilter
LinkedList<URI> listUris = null; -> private LinkedList<URI> listUris = null;

> Oozie distributes application jar twice making the spark job fail

> Oozie adds the application jar to the list of files to be uploaded to 
> distributed cache. Since this gets added twice, the job fails. This is 
> observed from spark 2.1.0 which introduces a check for same file and fails 
> the job.
