Re: [VOTE] Merge HDFS-3077 (QuorumJournalManager) branch to trunk
Hey Sanjay,

While I understand it's substantial and complex code, the code and the
design doc have been available for several months, and the community
has certainly been aware of its development. I also gave a heads up
last week that I would call a merge this week. So I feel like there
has been sufficient time for interested parties to review.

That said, since I was sick for much of this week and not immediately
responsive to some of the questions from you and Suresh, I'm happy to
agree to postpone the merge to early next week. Let's extend the vote
to last until Monday end of day PST.

Of course if there are follow-up questions or bugs found after the
merge, you've all got my phone number and I'm not going anywhere! ;-)
