-------------------------------

[~stevel@apache.org] Thanks for taking on this masochistic task.  Given hadoop surface area,
it is hard to figure if a dependency is needed.  How about we go radical in trunk since it
will be ten years before there is a hadoop3 which should be time enough to figure those dependencies
removed that should have been left in.  hadoop2 could do w/ a just a purge of at least the
just-not-used.  I'd like to help out.  In hbase we put on a few filters to try and block the
plain farcical but god-bless-maven, you have to reproduce this set each time for each hadoop
version we build against since no xinclude...

> If you try using Hadoop downstream with a classpath shared with HBase and Accumulo, you
soon discover how messy the dependencies are.
> Hadoop's side of this problem is
> # not being up to date with some of the external releases of common JARs
> # not locking down/excluding inconsistent versions of artifacts provided down the dependency
