Subject Re: Discussion: Move contribs out of hbase?
Date Thu, 28 Jan 2010 23:54:34 GMT
We could also have code coverage requirements for hbase contribs, or
any other code metrics we might want to ensure that we aren't shipping
utterly broken code.

I think the risk of being left out of a release packaging is the right
kind of impetus to get someone to work on their contrib. It would also
lower the barrier, and let us federate the source control (something
ASF doesnt officially support). The latter is most important i think.
I avoid SVN as much as possible :-)
