Subject [jira] Updated: (HADOOP-6629) versions of dependencies should be specified in a single place

Doug Cutting updated HADOOP-6629:

    Attachment: HADOOP-6629.patch

Here's a version of the patch that avoids log4j's dependencies by making it an optional dependency
of hadoop-common.  The hadoop-mapreduce module already directly depends on log4j so this generates
a pom that works with hadoop-mapreduce, i.e., one can use 'ant mvn-install -Dresolvers=local'
and an ivy-created pom is published such that mapreduce can be compiled and tested.

That said, I still don't get Ivy's configurations, and may have made a hash of them.

> Currently the Maven POM file is generated from a template file that includes the versions
of all the libraries we depend on.  The versions of these libraries are also present in ivy/libraries.properties,
so that, when a library is updated, it must be updated in two places, which is error-prone.
 We should instead only specify library versions in a single place.
