MR-279: Install sanitized poms for downstream sanity
----------------------------------------------------
Key: MAPREDUCE-2432
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2432
Project: Hadoop Map/Reduce
Issue Type: Improvement
Reporter: Luke Lu
Assignee: Luke Lu
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.
