>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2432
>             Project: Hadoop Map/Reduce
>          Issue Type: Improvement
>          Components: mrv2
>            Reporter: Luke Lu
>            Assignee: Luke Lu
>             Fix For: 0.23.0

> Due to [MNG-4223|http://jira.codehaus.org/browse/MNG-4223], the installed POMs of MR-279
is downstream hostile. E.g., it's impossible to use versions of hadoop-mapreduce-client-core.version
in ivy other than 1.0-SNAPSHOT without changing the multiple POMs, rendering the version properties
(hadoop-mapreduce.version and yarn.version) practically useless.
> This patch will install POMs with version (only) properties expanded. This patch also
use inheritance and dependencyManagement to make POMs DRYer. It could use further cleanup
to reduce "unnecessary" dependencies in some modules, but it's a working start.
> To see the patch work, apply the patch and do a mvn clean install -P-cbuild -DskipTests
to make sure sane POMs are installed and then working on individual test issues.
