I was dreading this response! Are there any plans to push out a new Hive
build with the latest features & bug fixes? Building from trunk is not
everyone's cup of tea, you know :-)

Any nightly builds that I can pick up?

Saurabh.

I agree. I do not know the answer to that one. Can anyone comment on the
future Hive release schedule?

Hive 4.0 will be a release candidate soon. The largest major blocker
that I know of is dealing with Hadoop 0.20. See:

https://issues.apache.org/jira/browse/HIVE-487

Soon after that their should be a release candidate, then voting.

Is there any possibility of having a nightly build off the trunk,
before hive 0.4 is officially released?

The major thing on that is we have to build releases for every hadoop
major/minor and possibly one off the trunk. I was thinking of doing
something similar on my site since accomplishing this is possible with
hudson. Does anyone think adding this to hadoop hive is something we
should do.

Re: JDBC: Infinite while(rs.next()) loop

Bill Graham 2009-08-04, 23:13

I would love to see nightly/periodic builds published somewhere, especially
if it's going to be some time before Hive 0.4 is released.

It seems like people new to Hive get the "check out and build from the
trunk" or "apply this patch" answer often on this list. Having nightly
builds would make life easier on these folks as well.

A nightly build is helpful for newbies who don't have the necessary skills
(or time) to build trunk themselves. For that class of people it doesn't
make any difference if the Hadoop version used is the latest -- in all
probability, they're new to Hadoop as well. Even if they have an older
version of Hadoop running in a production cluster, they would be fine with
downloading a newer version to experiment/develop with a *nightly build* of
Hive.

To summarize, a nightly build off Hadoop-0.3 should be just fine :-)

PS: I'm assuming that switching to a newer version of Hadoop is easy, and
data in the DFS can be imported into the newer version, right?

Saurabh.

Namit just committed Todd's patch of HIVE-487, so hive trunk is
already compatible with hadoop 0.20 now.

Bill, I feel your pain on the nightly releases. At any given time I am
working with four trunks, and two major hadoop versions. On a related
topic, I use linux-vserver.org I want to cook up a system that can
produce and test in distributed mode, something like hudson + vserver
to fire out 'appliances' but doing nightly should be pretty easy ill
start on that first.

RE: JDBC: Infinite while(rs.next()) loop

Ashish Thusoo 2009-08-05, 17:43

We will have to enable nightly builds with 0.20 on Hudson. That is still not done but can be enabled after we brnach. We can branch out 0.4 today or latest by Friday now that 487 is in.

RE: JDBC: Infinite while(rs.next()) loop

Ashish Thusoo 2009-08-05, 18:23

Just noticed that hudson is no longer doing the nightly builds for hive.

Johan had added hudson for doing nightly builds for hive. These are available at

http://hudson.zones.apache.org/hudson/job/Hive-trunk-h0.17/
http://hudson.zones.apache.org/hudson/job/Hive-trunk-h0.18/
http://hudson.zones.apache.org/hudson/job/Hive-trunk-h0.19/
They are also hang off from the developer menu on the Hive official page.

http://hadoop.apache.org/hive/

The links though don't seem to be working right now which may be a transient problem with hudson.

The major thing on that is we have to build releases for every hadoop
major/minor and possibly one off the trunk. I was thinking of doing
something similar on my site since accomplishing this is possible with
hudson. Does anyone think adding this to hadoop hive is something we
should do.

Yeay! The links are working now. Just confirming -- the build process runs
standard unit tests as part of the process, right? In case of test failures
it doesn't publish the build?

Sorry for the stupid question, but I can't find any link to actually
download the build (zip/tarball). Where do I download the build from?

You can access the builds for 0.3 from

http://hadoop.apache.org/hive/releases.html

I already have the 0.3 build. I was looking for the nightly trunk
builds. But, i guess those will be available after the hudson disk
space problem is sorted out.
