I basically gave up.  Most everyone I talked to at various meetups was enthusiastically supportive
of removing contrib components.  When put to a vote on list, however, most were vetoed by
1 or 2 people.

I guess so.  HDFS Proxy seems like an example of this.

I would support that as a fallback.

in SVN, leaving a wiki link to their most recent state and letting their contributors make

Agreed, but we couldn't reach consensus.

I'd like to start a discussion on moving contrib components out of common, mapreduce, and
hdfs.

 Most folks I've talked with agree that these contrib components would be better served by
being pulled out of Hadoop and hosted elsewhere. The new apache-extras code hosting site seems
like a natural *default* location for migrating these contrib projects.  Perhaps some should
graduate from contrib to src (ie from contrib to core of the project they're included in).
 If folks agree, we'll need to come up with a mapping of contrib component to it's final destination
and file a jira.
