      More information about the 2.8.0 release plan can be found here: https://cwiki.apache.org/confluence/display/HADOOP/Hadoop+2.8+Release

      New RC is available at: http://home.apache.org/~junping_du/hadoop-2.8.0-RC3

      The RC tag in git is: release-2.8.0-RC3, and the latest commit id is: 91f2b7a13d1e97be65db92ddabc627cc29ac0009

      The maven artifacts are available via repository.apache.org at: https://repository.apache.org/content/repositories/orgapachehadoop-1057

      Please try the release and vote; the vote will run for the usual 5 days, ending on 03/22/2017 PDT time.

Thanks,

Thanks, testing in progress

here's the windows native binaries to go with it, all signed

https://github.com/steveloughran/winutils/releases/tag/hadoop-2.8.0-RC3

The gnu shell commands which came with git worked well here, and the build went through fast, nice to see

Test results to follow

+1 (non-binding). Thanks Junping for the effort.

I have used release package and verified below cases
- Ran MR sleep job and wordcount successfully in where nodes are configured
with labels.
- Verified application priority feature and I could see high priority apps
are getting resource over lower priority apps when configured
- Verified RM web UI pages and looks fine (priority could be seen)
- Intra-queue preemption related to app priority also seems fine

Thanks
Sunil

1. None of the kerberos auth tests like me
2. many of the hadoop-common failures were test side, with some more diagnostics, fixed
https://issues.apache.org/jira/browse/HADOOP-14201
3. All the hadoop-aws integration tests worked

I had problems with: gzip code and some of the IPC tests, those being so foundational that it helps convince me that the network is somehow at fault, like the VM isn't coming up right.

Can other people with windows development setups do a run of this?

I've not done any other testing, Windows was enough for a weekend afternoon

Tested from the released binary package
* 5 node cluster running from dockerized containers (every namenode/datanode/nodemanager, etc. are running in separated containers)
* Bitcoin bockchain data (~100Gb) parsed and imported to HBase (1.2.4)
* Spark (2.1.0 with included hadoop) job (executing on YARN) to query the data from HBase and write the results to HDFS

Looks good.

https://dist.apache.org/repos/dist/release/hadoop/common/KEYS. So it would be nice if those were in sync. 
Compiled from source
Deployed pseudo-distributed cluster
Ran some sample MR jobs


we need to do more key signing; the stuff in the various KEYS files have aged

Alll ASF Committers can publish their ASF keys:


which you can retrieve on a committer-by-committer basis : 


Committers should log in to https://id.apache.org/ and set them.

Maybe that committer page should just be declared as the reference place to find keys; It bootstraps off the ASF HTTPS certificate for trusted D/L, and relies on login credentials being kept secure. But if not, well, people can publish code under your login, so signing is the least concern.

Discovered https://issues.apache.org/jira/browse/HADOOP-14205 "No
FileSystem for scheme: adl".

The issue were caused by backporting HADOOP-13037 to branch-2 and earlier.
HADOOP-12666 should not be backported, but some changes are needed:
property fs.adl.impl in core-default.xml and hadoop-tools-dist/pom.xml.

I am working on a patch.

Re: [VOTE] Release Apache Hadoop 2.8.0 (RC3)

Junping Du-2
Thank you for reporting the issue, John! Does this issue only affect ADL (Azure Data Lake) which is a new feature for 2.8 rather than other existing FS? If so, I think we can leave the fix to 2.8.1 to fix given this is not a regression and just a new feature get broken.?


Thanks,


Junping

?Thanks for update, John. Then we should be OK with fixing this issue in 2.8.1.

Mark the target version of HADOOP-14205 to 2.8.1 instead of 2.8.0 and bump up to blocker in case we could miss this in releasing 2.8.1. :)


Thanks,

Yes, it only affects ADL. There is a workaround of adding these 2 properties to core-site.xml:

  <property>
    <name>fs.adl.impl</name>
    <value>org.apache.hadoop.fs.adl.AdlFileSystem</value>
  </property>

  <property>
    <name>fs.AbstractFileSystem.adl.impl</name>
    <value>org.apache.hadoop.fs.adl.Adl</value>
  </property>

I have the initial patch ready but hitting these live unit test failures:

Failed tests:
  TestAdlFileSystemContractLive.runTest:60->FileSystemContractBaseTest.testListStatus:257 expected:<1> but was:<10>

Tests in error:
  TestAdlFileContextMainOperationsLive>FileContextMainOperationsBaseTest.testMkdirsFailsForSubdirectoryOfExistingFile:254 » AccessControl
  TestAdlFileSystemContractLive.runTest:60->FileSystemContractBaseTest.testMkdirsFailsForSubdirectoryOfExistingFile:190 » AccessControl


Stay tuned...

Hi Steve,

I said this in a previous email in this thread, but per INFRA we're not to
rely on the keys set on id.apache.org for release verification. Keys need
to be added to the dist KEYS file.

Best,
Andrew

Hi,
        I have used release package and verified basic operations for HDFS.
        I raised one blocker issue for this release.

        HADOOP-14207 : "dfsadmin -refreshCallQueue" command is failing with DecayRpcScheduler
       
Thanks,
Surendra

Thanks Junping!

+1 (binding)

* Verified signatures and checksums
* Built Hive 2.1.0 and Tez 0.8.5 with Hadoop 2.8.0 pom
* Deployed a single node cluster and ran some Hive on Tez queries
successfully
* The document looks good.

I found a trivial issue in the doc. It does not block the release.

Re: [VOTE] Release Apache Hadoop 2.8.0 (RC3)

Wei-Chiu Chuang
Thanks Junping for taking on this huge effort!

I found one tiny nit: the md5 files are not in conventional format
That is to say,
$ cat hadoop-2.8.0.tar.gz.md5

$ /usr/bin/md5sum /build/source/target/artifacts/hadoop-2.8.0.tar.gz
c728a090b68d009070085367695ed507  /build/source/target/artifacts/hadoop-2.8.0.tar.gz

But a typical md5 file would have been:
c728a090b68d009070085367695ed507  hadoop-2.8.0.tar.gz

I was pretty stunned finding hadoop-2.8.0.tar.gz is a whopping 410MB binary, comparing to hadoop-2.7.3.tar.gz which is just 205 MB.
But later on I realized the source code hadoop-2.8.0-src.tar.gz is 33MB comparing to hadoop-2.7.3-src.tar.gz which is 18MB. So probably it’s the amount of changes made into Hadoop 2.8 makes such difference in size.

Regards,
Wei-Chiu Chuang

Re: [VOTE] Release Apache Hadoop 2.8.0 (RC3)

Andrew Wang
I poked around a bit. The 3.0.0-alpha2 binary tarball is only 246M and has
more changes than 2.8.0.

It looks like the 2.8.0 bin tarball has an extra 1.5GB of docs when
extracted compared to 3.0.0-alpha2. I think it's from the extra src-html
content:

-> % find share/doc -name src-html | xargs du -sb | awk -e '{SUM+=$1} END
{print SUM}'

Thanks Junping for working on the new release!

+1 non-binding

1) Downloaded the source, verified the checksum
2) Built natively from source, and deployed it to a pseudo-distributed
cluster
3) Ran sleep and teragen job and checked both YARN and JHS web UI
4) Played with yarn + mapreduce command lines

Best,
Haibo Chen

Re: [VOTE] Release Apache Hadoop 2.8.0 (RC3)

Steve Loughran-3

I'm an =0 I'm afraid

I think those extra files need to be pulled which triggers a repackage, at which point there's a couple of

HADOOP-14205 No FileSystem for scheme: adl
HADOOP-14204 S3A multipart commit failing,

of the two, the ADL FS one is the most significant, though if there was going to be a re-roll, I'd like them in.

I also worry about windows test coverage, as irrespective of whether people are planning to run it on a windows host in production, the hadoop libs get used client side in job submit, and more now in Spark . HADOOP-14201 showed up that (a) my new VM is a mess, so complicating testing and (b) gzip was failing. I Worry about gzip, as that could be a sign of native lib problems.. someone needs to look at it a bit more. However, I don't think it should really be a blocker, given the ASF doesn't officially redistribute windows binaries.

so: some issues with packaging and a couple of patches which need to go in. Test coverage on windows is potentially longer, and I don't want it to hold things up.

Anyhow: =0. If everyone else is happy to ship, then let's get it out the door, as that's the only way that we'll get all the in-the-field bugreps coming back in. We will need to release some new versions in the coming weeks to handle those

-Steve

Re: [VOTE] Release Apache Hadoop 2.8.0 (RC2)

In reply to this post by Junping Du-2
Thanks for taking the mantle from me on 2.8.0 and some persistent work getting 2.8.0 out the door, Junping!

Apologies for bringing this up late, but I’d like to add one comment.

We should repeat what we did for 2.7.0 and In line with our experience there, we should annotate this release as not ready for production use. See the releases page - http://hadoop.apache.org/releases.html#25+August%2C+2016%3A+Release+2.7.3+available for our messaging on 2.7.0.

The expectation is that more downstream projects pick up the bits, iron out any incompatibilities we might have missed, and production users then pick up a solid 2.8.1.

Thanks
+Vinod
