Thanks,Vinod, for the time and effort you put into creating this release.

I downloaded and built the source for 2.7.0, RC0. I started a local cluster and ran wordcount,
sleep, and streaming jobs.

In addition, I did the following:
    o I ran a distributed shell job which tested preserving containers across AM restarts.
I did this by setting the -keep_containers_across_application_attempts flag and killing the
first AM once the containers started. I checked the results by querying the timeline server
and comparing the start and end times of the non-AM containers against the start and end times
of the later AM containers. This verified that the non-AM containers started during the first
AM's run and finished after the first AM had been killed and after the second AM had started.

    o I enabled the preemption feature and verified that containers were preempted from
preemptable queues and not from non-preemptable ones.
    o I ran unit tests for hadoop-yarn-server-resourcemanage. All passed with the exception
of TestFifoScheduler#testResourceOverCommit. 
    o I ran unit tests for hadoop-yarn-server-nodemanager. All passed with the exception
of TestResourceLocalizationService#testFailedDirsResourceRelease.

    o I ran unit tests for hadoop-hdfs. All passed with the exception of TestReplaceDatanodeOnFailure#testReplaceDatanodeOnFailure,TestBalancer#testUnknownDatanode,
TestBPOfferService#testBasicFunctionality, and TestWebHdfsFileSystemContract#testGetFileBlockLocations.
  Thank you,-Eric Payne

 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 at

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 on
how it goes, get it stabilized and potentially use a 2.7.1 in a few
weeks as the stable release.

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


 [1]: A 2.7.1 release to follow up 2.7.0
