[jira] [Created] (YARN-5530) YARN dependencies are a complete mess

Allen Wittenauer created YARN-5530:
--------------------------------------

             Summary: YARN dependencies are a complete mess
                 Key: YARN-5530
                 URL: https://issues.apache.org/jira/browse/YARN-5530
             Project: Hadoop YARN
          Issue Type: Bug
          Components: build
    Affects Versions: 3.0.0-alpha1
            Reporter: Allen Wittenauer


YARN's share/hadoop/yarn/lib is pretty much a disaster area.  Multiple jars have multiple versions.  Then there are the version collisions with the rest of Hadoop.  Oh, and then there are the test jars sitting in there.

This really needs to get cleaned up since all of this stuff is on the classpath and are likely going to cause a lot of problems down the road, never mind the download bloat. (trunk's yarn dependencies are 2x what they were in branch-2, thereby eliminating all the gains made by de-duping jars across the projects.)
