Great! So how far is a release candidate or nightly build now ?

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

We have added some examples and general guide on how to write a new
SerDe and UDF/UDAF.

Another line of reasoning -- if Hive-trunk is not compiling with Hadoop
0.20, then people with Hadoop 0.20 are anyways living with their bugs. That
should not be a reason to not put out a new build. With a new build, at
least people who're on newer versions of Hadoop get their Hive bug fixes &

That's the first thing I noticed -- lack of native date format. However, if

Hadoop Fans, it looks like most of you prefer to have this on Thursday
(November 5th), so that's what we'll plan for.
Anyone is welcome to come to this meetup, even if you don't attend
ApacheCon. We'd love to hear more about various sub-projects and cool
Hadoop applications, tips, tricks, etc.

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 lif
We don't have such a udf right now, but it is extremely easy to write one.
Take a look at this (and search for UDF):

Everything inside the quotes will be executed using a shell, similar to that of
Hadoop Streaming. Unless Hadoop Streeaming changes, Hive would not. And it is
highly unlikely that Hadoop Streaming changes since lot of people are dependent
on it.

Prasad, my query was more about the concept. Not the syntax. I hope
this will still work when hive 0.4 is released. I'm basing a lot on
it.

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

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

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?

This bug has been fixed on the trunk. Check out the hive trunk and build the
JDBC driver and you should be fine.

Hi Ashish, thanks for help!
1) regarding the group-by-week, it was entirely my fault... I miswrote
the function... to get grouping by week one needs to have
FIELD: date_add('2007-12-31', (datediff(date_field, '2007-12-31') / 7) *
7)
GROUP BY: datediff(date_field, '2007-12-31') / 7
This then works

Y, hive support column-based storage. RCFile. You can create a table using
command like :
Create table tbl(cols) stored as RCFile
to try Hive's column storage.

Hi to all Hivers out there!
Does Hive currently support column-based storage?
For example, can we use HBase tables as Hive table inputs for HQL?
