Thanks, Vinod, for working so hard on each 2.7 release.

+1 (non-binding)

Here's what I did:

- Built native 
- Installed on 3-node unsecure cluster
- Configured 2 queues with 2 separate label partitions 
- Verified that a job will successfully run on the correctly labelled node by specifying a
non-default (but queue-accessible) label. 
- Verified that a distributed shell job would keep non-AM containers running across an App
Master attempt restart. 
- Verified that preemption happens as expected (sort of). I say "sort of" because about twice
as many containers were preempted as I thought should have been, but once the other underserved
app began to run, it stopped preempting. Also, it didn't preempt between 2 queues with the
same partition label. Partition preemption may not be supported in 2.7, so this is probably
also okay.

Subject: [VOTE] Release Apache Hadoop 2.7.3 RC2

Hi all,

I've created a new release candidate RC2 for Apache Hadoop 2.7.3.

As discussed before, this is the next maintenance release to follow up 2.7.2.

The RC is available for validation at: http://home.apache.org/~vinodkv/hadoop-2.7.3-RC2/ <http://home.apache.org/~vinodkv/hadoop-2.7.3-RC2/>

The RC tag in git is: release-2.7.3-RC2

The maven artifacts are available via repository.apache.org <http://repository.apache.org/>
at https://repository.apache.org/content/repositories/orgapachehadoop-1046 <https://repository.apache.org/content/repositories/orgapachehadoop-1046>

The release-notes are inside the tar-balls at location hadoop-common-project/hadoop-common/src/main/docs/releasenotes.html.
I hosted this at http://home.apache.org/~vinodkv/hadoop-2.7.3-RC2/releasenotes.html <http://home.apache.org/~vinodkv/hadoop-2.7.3-RC2/releasenotes.html>
for your quick perusal.

As you may have noted,
- few issues with RC0 forced a RC1 [1]
- few more issues with RC1 forced a RC2 [2]
- a very long fix-cycle for the License & Notice issues (HADOOP-12893) caused 2.7.3 (along
with every other Hadoop release) to slip by quite a bit. This release's related discussion
thread is linked below: [3].

Please try the release and vote; the vote will run for the usual 5 days.
