Eric Charles commented on HADOOP-6671:
--------------------------------------

Hi,
Jenkins haddop-common-trunk is blue (builds fine).
I've downloaded https://builds.apache.org/job/Hadoop-Common-trunk-maven/13/artifact/trunk/target/hadoop-common-0.23.0-SNAPSHOT.tar.gz
and imported it in eclipse via m2eclipse. Still need to add 3 folders in my build path to
have operation project in eclipse: target/generated-sources/avro-protocol, avro-schema and
record-cc (Maybe this can be solved with the build-helper-maven-plugin : http://www.sonatype.com/people/2008/05/adding-additional-source-folders-to-your-maven-build/)

When I run "mvn test" in shell, I've got two failures in TestUserGroupInformation [1], however
the TestUserGroupInformation run from eclipse works fine.
Seems like UserGroupInformation behaves differently in shell than in eclipse. Same issue if
I run "mvn test -P os.mac" (I run on mac).

> We are now able to publish hadoop artifacts to the maven repo successfully [ Hadoop-6382]
> Drawbacks with the current approach:
> * Use ivy for dependency management with ivy.xml
> * Use maven-ant-task for artifact publishing to the maven repository
> * pom files are not generated dynamically 
> To address this I propose we use maven to build hadoop-common, which would help us to
manage dependencies, publish artifacts and have one single xml file(POM) for dependency management
and artifact publishing.
> I would like to have a branch created to work on mavenizing  hadoop common.
