Hadoop 0.20.1 (a big secret?)
Howdy,
I'm about to install a new hadoop cluster here and I'm wondering which
Hadoop to install.
Looking at http://hadoop.apache.org/common/releases.html suggests its
either 0.19.2 or 0.20.0 but looking in
http://ftp.heanet.ie/mirrors/www.apache.org/dist/hadoop/core/ I see
0.20.1 has been sitting there since 01-Sep-2009.
A quick google suggests Cloudera are going to base their next release on
0.20.1 so I'm taking this as an indication that 0.20.1 is ready for
primetime.
Did I miss the announcement on 0.20.1 or is there some reason why it's
being kept quiet so far (if so, apologies for publicising it ;)?
Thanks,
-stephen

1 Sep 2009 was when I rolled the release candidate. I pushed the
documentation changes yesterday, so they should be visible today. When
they are visible, I'll send the announcement out. The 0.20.1 release
is looking like a stable release and if I was setting up a cluster,
I'd use it.

For new clusters we recommend the 0.20 branch. There will probably be some
more point releases beyond 0.20.1 down the road, but I would classify 0.20
as stable enough for production clusters at this point. There may be
slightly more problems than 0.18.3, but I don't know of any commonly
occurring issues that are unfixed.

Hi.
Do you think that 0.20.1 will be the next stable version (like 0.18.3?)
We will install Hadoop in a cluster soon (maybe this week). Which
version do you recommend?

This may be related to the project split. When I went to package up 0.20.1,
I realized that the release-0.20.1 tag is not in the hadoop repository but
rather the hadoop-common repository. Important to know if you want to build
0.20.1 from subversion/git.

Just as a note the project releases page for common/hdfs/mapreduce (e.g. http://hadoop.apache.org/mapreduce/releases.html ) do not have an entry for the 0.20.1 release, but going to the download link shows 0.20.1 as the stable release for the .20 branch.
I suspect that is a cause of the confusion.

Stephen,
Hadoop has branches and for the most part, major.minor.release
versioning. If you look at the svn-trunk you are always going to be
latest branch. At the current moment stable points to 18.X.
It seems the trend community is really trying to come together around 20.
Here is some quick notes:
Hadoop updgrade is easy.
Downgrade between majors can be a major pita.
I would suggest playing with the technology for a while and get a feel
for the version that is best for you.

Stephen,
Hadoop has branches and for the most part, major.minor.release
versioning. If you look at the svn-trunk you are always going to be
latest branch. At the current moment stable points to 18.X.
It seems the trend community is really trying to come together around 20.
Here is some quick notes:
Hadoop updgrade is easy.
Downgrade between majors can be a major pita.
I would suggest playing with the technology for a while and get a feel
for the version that is best for you.

Hi Stephen,
There was an email thread about two weeks ago announcing the release
candidate and subsequent release.
Regarding Cloudera's version, the most recent one available for download is
based on 0.20.0, but we've included many of the bug fixes that are in
0.20.1. We're currently working on updating our patch series to include the
entirety of 0.20.1 and should have that out next week.
