> 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, oya
> Reporter: Robert Kanter
> Assignee: Attila Sasvari
> Attachments: OOZIE-2316-001.patch, OOZIE-2316-002.patch,
> OOZIE-2316-003.patch
>
>
> 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".
