> Currently, multiple versions of the same library JAR are being pulled in for various
reasons.
> * Within the same project, multiple versions of the same JAR are pulled in. E.g. Avro
(used by Common) depends on Commons Lang 2.5 while Common depends on Commons Lang 2.4.
> * Dependent subprojects use different versions. E.g. Common depends on Avro 1.3.2 while
MapReduce depends on 1.3.0. Since MapReduce depends on Common, this has the potential to cause
a problem at runtime.
