I assume we will make sure the HDFS mavenization is in before then?
Tom said he intends to commit it tomorrow, but if something comes up
and it's not committed, let's make sure mavenization happens before we
branch.

Also, what will be the guidelines for committing a change to 0.23
branch? Is it "bug fix only" or are we still allowing improvements?
Given how recently MR2 was merged, I imagine there will be a lot of
things that aren't strictly bugs that we will really want to have in
our next release. I also have a couple of HDFS patches (eg the new
faster CRC on-by-default) that I'd like to get into 23.
