             Summary: Drop support for Hadoop 1 and 0.23
                 Key: OOZIE-2316
                 URL: https://issues.apache.org/jira/browse/OOZIE-2316
             Project: Oozie
          Issue Type: Bug
    Affects Versions: trunk
            Reporter: Robert Kanter


Given that Hadoop 2.x has had many releases now (2.8 is next), Hadoop 1.x hasn't had a release in a really long time, and Hadoop 3.0 is coming somewhat soonish, it would be good to drop support Hadoop 1.x and Hadoop 0.23.  I believe most users are using Hadoop 2.x anyway.

This should help simplify the build a lot as we can probably get rid of the hadooplibs stuff and don't need to set Hadoop 1 and Hadoop 2+ properties (e.g. JT and RM addresses), so we can get rid of those cases as well.

It might also be good to create new versions of the schemas that use {{<resource-manager>}} instead of {{<job-tracker>}} (the existing schemas would of course still work).  While this is a minor thing, it does bring up questions every so often of "does Oozie support Hadoop 2/YARN?"  And "how do I specify the RM?"  Alternatively, we could update the existing schemas to allow one of {{<resource-manager>}} or {{<job-tracker>}}.  I'm not sure what we should do about any config properties in Oozie site that mention "job-tracker".
