+1 non-binding
Ran a performance comparison of 2.6.0 Latest with 2.7.0 RC, looks good, no 
regressions observed, most metrics are well within 5%  tolerance (dfsio, sort, 
amrestart, gmv3) and some tests (scan, amscale, compression, shuffle) appear to 
have improvements. 

Disclaimer, please note a JDK difference, 2.6.0 ran with jdk1.7 while 2.7.0 had 
jdk1.8, so some of the improvement may be from Java 1.8.0, that said, the 2.7.0 
benchmarks compare well against current 2.6.0.
Thanks.

 Subject: [VOTE] Release Apache Hadoop 2.7.0 RC0
   Hi all,
I've created a release candidate RC0 for Apache Hadoop 2.7.0.
 The RC is available at: http://people.apache.org/~vinodkv/hadoop-2.7.0-RC0/
The RC tag in git is: release-2.7.0-RC0
 The maven artifacts are available via repository.apache.org 
athttps://repository.apache.org/content/repositories/orgapachehadoop-1017/
As discussed before - This release will only work with JDK 1.7 and above - I’d 
like to use this as a starting release for 2.7.x [1], depending onhow it goes, 
get it stabilized and potentially use a 2.7.1 in a fewweeks as the stable 
release.
 Please try the release and vote; the vote will run for the usual 5 days.
 Thanks, Vinod
 [1]: A 2.7.1 release to follow up
