> Clean up duplication of dependent jar files
> -------------------------------------------
>
> Key: MAPREDUCE-2483
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2483
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: build
> Affects Versions: 0.23.0
> Reporter: Eric Yang
> Assignee: Eric Yang
> Attachments: MAPREDUCE-2483.patch
>
>
> For trunk, the build and deployment tree look like this:
> hadoop-common-0.2x.y
> hadoop-hdfs-0.2x.y
> hadoop-mapred-0.2x.y
> Technically, mapred's the third party dependent jar files should be fetch
> from hadoop-common and hadoop-hdfs. However, it is currently fetching from
> hadoop-mapred/lib only. It would be nice to eliminate the need to repeat
> duplicated jar files at build time.
> There are two options to manage this dependency list, continue to enhance ant
> build structure to fetch and filter jar file dependencies using ivy. On the
> other hand, it would be a good opportunity to convert the build structure to
> maven, and use maven to manage the provided jar files.
