Hi Colin,

Thanks for closing the previous VOTE.  (We usually count the numbers of +1's and -1's, and
then state whether the vote passes.  Hope that you could include such information next time.)

I withdraw my -1.

The patch in HDFS-4661 has addressed the problem I raised.  Once the previous VOTE has be
concluded, I will remove my -1.  Thanks.

We usually conclude the last VOTE before starting a new one.  Otherwise, people may be confused
between the VOTEs.  (In case you don't know our convention.  Please check with someone before
starting a VOTE.  Thanks.)

* The previous VOTE started by Colin has not been concluded.

* The branch is not ready.  The code misuses DataTransferProtocol.  Documentation of the
new conf properties are missing.  Also, the code in the branch needs to be polished.  See
HDFS-347 and HDFS-4661 for more details.

 HDFS-347 merge

Hi all,

I think it's time to merge the HDFS-347 branch back to trunk.  It's been under
review and testing for several months, and provides both a performance
advantage, and the ability to use short-circuit local reads without
compromising system security.

Previously, we tried to merge this and the objection was brought up that we
should keep the old, insecure short-circuit local reads around so that
platforms for which secure SCR had not yet been implemented could use it
(e.g. Windows).  This has been addressed-- see HDFS-4538 for details.
Suresh has also volunteered to maintain the insecure SCR code until secure
SCR can be implemented for Windows.

Please cast your vote by EOD Monday 4/8.
