Major Description
If you build a Hadoop tarball with a non-release version, the moduleSet used in hadoop-assemblies/src/main/resources/assemblies/hadoop-mapreduce-dist.xml results in jar files going into share/hadoop/mapreduce with unique snapshot versions - i.e., the timestamp they were built. This isn't an issue in release builds. It can be fixed by adding " <outputFileNameMapping>${module.artifactId}-${project.version}${dashClassifier?}.${module.extension}</outputFileNameMapping>" to the binaries tag of the moduleSet.
