Todd Lipcon commented on HDFS-4179:
-----------------------------------
OK, to be clear: I'm not interested in reviewing it, because I don't see what
the BN offers aside from other already-existing approaches. So, I can't
personally devote time to it.
And I don't think "no one wants to review this" is valid reason to commit
without a review.
