Subject Re: [VOTE] Release Apache Hadoop 2.7.0 RC0
Date Tue, 14 Apr 2015 21:18:15 GMT
+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 2.7.0http://markmail.org/thread/zwzze6cqqgwq4rmw
