Drew Farris commented on MAHOUT-224:
------------------------------------
${hadoop.version} is used in the version tag of the hadoop dependency defined
in the dependencyManagement section of mahout/maven/pom.xml - since it is
defined and used in the same file it is not strictly necessary, but I thought
it would be worthwhile to keep this near the defined properties for the other
major dependencies such as lucene and junit.
The parent of mahout/maven/pom.xml has been changed from mahout/pom.xml which
was at 0.3-SNAPSHOT to org.apache:apache (which is the parent of
mahout/pom.xml), which is at 6. This makes mahout/maven/pom.xml (the parent
pom) and mahout/pom.xml (the primary module pom) siblings.

> In preparation for the binary release work described in MAHOUT-215, here's a
> minor patch that does some some cleanup on the poms.
> The hadoop and junit dependency versions are now established using the
> dependencyManagement section of the parent pom in mahout/maven/pom.xml
> A large number of transitive dependencies from the hadoop pom are now
> excluded there as well -- these were not necessary previously because the
> hadoop dependency was hand-rolled and did not include them. With the update
> to the hadoop 0.20.2-SNAPSHOT, they now become required.
> Also, the parent pom no longer has mahout/pom.xml as its parent, this allows
> binary packaging to be performed in mahout/pom.xml after the build of all of
> the other sub-modules is complete.
> Also, removed the javamail dependency -- was there a reason this was present?
> Verified that build and unit tests complete.
