Good Morning,
Release candidate 0.20.205.0-rc1 is available at
http://people.apache.org/~mattf/hadoop-0.20.205.0-rc1/
A copy of the Release Notes are provided at the top level of that directory.

You are invited to download and evaluate it, then vote on accepting it as a
public release.
Voting will close at 9am GMT on Monday 10 October.

I was not able to successfully stage to the maven repo.  I will continue
trying in a few hours.

This RC isn't perfect, but has passed the vast majority of system tests
applied to date, without any failures currently known to be blockers.  These
are the biggest known issues:

HDFS-2386 - fsck calls lead to handshake_failure and hftp fails throwing the
same exception in the logs  - This bug has only been seen on one cluster and
did not reproduce on 3 others.  It is currently believed to be a
configuration error on a faulty cluster.

MAPREDUCE-3122 - -libjars with streaming does not create symlink in the cwd
of task - This bug was in 204, and no one saw it and posted a jira, so it
does not seem to be a blocker.

There are a few patches which were applied to 0.20.205, which are needed in
trunk but not yet provided.  I am in the process of tracking these down and
contacting the contributors to do likewise in trunk.
Please consider downloading this RC and giving feedback on it.  Thank you
very much.

--Matt
RM for 0.20.205.0

Many thanks to the community members who tried out RC1, and found several
critical or blocker bugs.
These have been resolved and I have now posted RC2 at
http://people.apache.org/~mattf/hadoop-0.20.205.0-rc2/
A copy of the Release Notes are provided at the top level of that directory.
Appropriate artifacts have also been pushed to the Maven staging repo.

Please download and evaluate it, then vote on accepting it as a public
release.
Voting will close at 1am GMT on Saturday 15 October  (6pm PDT, Fri 14 Oct).

Best regards,

Deployed to a cluster of 20 servers, with security and append features enabled.
Passed our internal test suite. Looks good!

I deployed on 5 node cluster with security turned on and ran mapreduce jobs.
Verified md5 signature of the rpm.

+1.

Checksums and signatures were OK.

I also ran an API compatibility check
(https://issues.apache.org/jira/browse/HADOOP-7035,
https://github.com/tomwhite/hadoop-compatibility-tools) and it passed.
There were three errors, all false positives:

Class org.apache.hadoop.fs.HarFileSystem
  "E1.2 - API type removed" : field public final static int
org.apache.hadoop.fs.HarFileSystem.VERSION = 1

Class org.apache.hadoop.mapred.JobClient
  "E1.2 - API type removed" : method public
org.apache.hadoop.io.Writable
org.apache.hadoop.mapred.JobClient.getQueueAclsForCurrentUser()

Class org.apache.hadoop.mapred.TaskTracker$LocalStorage
  "E1.2 - API type removed" : CLASS public static
org.apache.hadoop.mapred.TaskTracker$LocalStorage

In the first, the value changed from 1 to 3, which is a problem for
clients that reference these constants. We recommend that users
recompile their code, so this is not a problem. Still, we could
improve this situation in future
(http://stackoverflow.com/questions/3524150/is-it-possible-to-disable-javacs-inlining-of-static-final-variables).

The second is is because getQueueAclsForCurrentUser returns a
QueueAclsInfo (a Writable) which was made public in 205.

The third is for a private inner class.

Cheers,
Tom

Downloaded release, verified checksums and ran a single node cluster.

I downloaded the tar ball and deployed on a 6 node cluster with security
disabled. I put a few files and ran a few MR jobs, mostly to calculate the
value of Pi. All worked fine.

Curiously, the estimated value of Pi was once determined to be
"4.00000000000000000000", but I suspect this is a function of the parameters
I gave the Pi job, and not of any deficiency of the RC of 0.20.205. :)

+1. Downloaded the bits, set up a single node cluster and ran example
jobs. Works fine.

Exercised Hadoop 0.20.205 with HBase 0.90.4+, Pig 0.9.1+, Chukwa trunk on 20 nodes clusters, works fine.

Deployed on a single node and a 20node cluster with security turned on and
off. Ran Hadoop benchmarks, a few end-end tests and functional tests
covering distributed cache, capacity scheduler, decommissioning etc
Also ran end-end tests on Pig 0.9.x and a few system tests on Hbase 0.90.x
and Hive 0.7.x. Works convincingly fine.

No blocking issues found in Yahoo QE regression testing.
Performance testing showed no performance regression when compared with
204.

The vote has closed, with the following tally (including my own non-binding
+1):
    +1 binding:  4
    +1 non-binding: 6
    -1 binding: 0
    -1 non-binding: 0

The vote passes, ten to zero, with four PMC members voting in favor.  We
have a 0.20.205.0 release,
with both security and append/hflush!  Thanks to everyone who contributed
bug fixes, merges, and improvements.  It was truly a community effort.

I will announce on general@ as soon as I finish the mechanics of the
release.
Have a great weekend!
