0.19.2 release needed
I would like to see a 0.19.2 release soon.
0.19.2 appears to be stalled. I would like to see the stalled items pushed to 19.3 and a release of the more important items already fixed soon. Most of the more important fixes are already released in 0.20.0 . . .
http://issues.apache.org/jira/browse/HADOOP/fixforversion/12313650
19.2 currently has 20 Critical fixes that were resolved or closed since 19.1 and many other important improvements.
Many open issues have not been touched in a month or more.
I have been hit by the following fixed issues recently, and indications based on comments in the core-user mailing list is that I'm not alone:
http://issues.apache.org/jira/browse/HADOOP-5465
http://issues.apache.org/jira/browse/HADOOP-5241
http://issues.apache.org/jira/browse/HADOOP-5231
http://issues.apache.org/jira/browse/HADOOP-5269
Its probably safe to say that using the 0.19.2 unreleased branch right now is probably a much more stable and safe version than the released 0.19.1.
http://issues.apache.org/jira/secure/IssueNavigator.jspa?reset=true&&pid=12310240&fixfor=12313650&resolution=-1&sorter/field=priority&sorter/order=DESC
The main issues pending are appends / sync() related and should be moved off to 19.3 - or forever as recent comments indicate this may wait until 0.21.
Additionally many of the current open tickets have patches and are close to being closed out. Yet, 75% of these haven't been touched in 3+ weeks.
Thanks,
-Scott

Yup, we've got one you could take out for a spin -- one of the HDFS
installs is fairly sizable, but doesn't hold anything important yet.

;) You have to remember that we're relatively very small in a very big
picture. That statement was just one of optimism about the 0.21.x
schedule.

presumably this means you have enough of a cluster to do some testing on
an RC?

So you've got geneva to hold back on going live until 0.21.x is stable?

Hey Scott,
We use 0.19.1 (plus some patches) heavily. The other CMS sites use
the same version -- represents about 600TB of user community :)
I'd be interested in seeing a 0.19.2 released. I was kind of hoping
lasting for a few months more on 0.19.x and then skip to 0.21.x prior
to LHC startup.

Yes, my previous message is really a question as to the status of the 0.19 branch in the community.
If it is essentially dead, I'd like to know ASAP and figure out how to migrate elsewhere soon. If it has life left, it looks ripe for another cut.
Rolling backwards to 0.18 faces several problems., and its unclear if 0.20 is better or worse than 0.19.1.
Thanks All,

Are there any committers sympathetic to Scott who would like to
volunteer to drive the 0.19.2 release forward? I think Y! skipped
directly from 0.18 to 0.20, and so is less inclined to make 0.19 releases.

Are there any committers sympathetic to Scott who would like to
volunteer to drive the 0.19.2 release forward? I think Y! skipped
directly from 0.18 to 0.20, and so is less inclined to make 0.19 releases.

Hi,
I would also be interested in having a 0.19.2 release, or even more
releases.
If you are starting to run your cluster, you don't know which version you
should take. Some releases were unstable (eg taskstrackers running out of
memory, or executing maps sequentially after a certain number of jobs,
multifileoutputformat not working with threads, ..). If we are upgrading to
a major version number, we are nearly always hitting a bug which makes our
system unreliable.
Also now with yahoo's release of their own version, what happens if I use
that version? Will there be more releases after that one from yahoo? Can I
migrate my cluster back to the official branch afterwards without losing
data?

I want to feed some mapside join patches in, time to get off my duff and
submit them :)

wouldn't it be better for the community to learn how to dot
releases when Yahoo does not.

I am still interested in seeing a 0.19.2 release soon. The 0.19.2-dev and 0.18.4-dev branches have been close to dormant for over a month, yet contain many critical fixes.
With the Yahoo distribution out there, 0.20.1 is a slightly lower priority for me. Additionally, several other components are not yet 0.20.x compatible anyway.
What does the rest of the community think?
