+1 (non-binding)
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
https://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 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.
Thanks,
Vinod
[1]: A 2.7.1 release to follow up 2.7.0
