> Using Hadoop from projects like Pig/Hive/Sqoop/Flume/Oozie or any in-house
> system that interacts with Hadoop is quite challenging for the following
> reasons:
> * *Different versions of Hadoop produce different artifacts:* Before Hadoop
> 0.23 there was a single artifact hadoop-core, starting with Hadoop 0.23 there
> are several (common, hdfs, mapred*, yarn*)
> * *There are no 'client' artifacts:* Current artifacts include all JARs
> needed to run the services, thus bringing into clients several JARs that are
> not used for job submission/monitoring (servlet, jsp, tomcat, jersey, etc.)
> * *Doing testing on the client side is also quite challenging as more
> artifacts have to be included than the dependencies define:* for example, the
> history-server artifact has to be explicitly included. If using Hadoop 1
> artifacts, jersey-server has to be explicitly included.
> * *3rd party dependencies change in Hadoop from version to version:* This
> makes things complicated for projects that have to deal with multiple
> versions of Hadoop as their exclusions list become a huge mix & match of
> artifacts from different Hadoop versions and it may be break things when a
> particular version of Hadoop requires a dependency that other version of
> Hadoop does not require.
> Because of this it would be quite convenient to have the following
> 'aggregator' artifacts:
> * *org.apache.hadoop:hadoop-client* : it includes all required JARs to use
> Hadoop client APIs (excluding all JARs that are not needed for it)
> * *org.apache.hadoop:hadoop-test* : it includes all required JARs to run
> Hadoop Mini Clusters
> These aggregator artifacts would be created for current branches under
> development (trunk, 0.22, 0.23, 1.0) and for released versions that are still
> in use.
> For branches under development, these artifacts would be generated as part of
> the build.
> For released versions we would have a a special branch used only as vehicle
> for publishing the corresponding 'aggregator' artifacts.
