Per the UDF definition at
http://hive.apache.org/docs/r0.7.0/api/org/apache/hadoop/hive/ql/exec/UDF.html,
I could potentially pass the configuration (e.g. path to configuration file) as
another argument to evaluate(). I could load the configuration on the first
call to evaluate() into a singlet
You can use UNION even if the tables are different:
SELECT *
FROM (
select_statement
UNION ALL
select_statement
) unionResult

Hi,
Is there a straightforward way to execute a query on rows from multiple
tables in Hive? Specifically, let's say that we have 2 tables A and B with
exactly the same schema. Is it possible for me to execute a query on all
the rows of A and B? If not, what could be the best way to alter the
table
An UDF can accept some params, you can pass your configuration in one of it?

Hi,
Is there a way to pass in some custom arguments to a UDF when initializing it?
I'd like to pass in some configuration parameters to a UDF, but didn't see a
way to readily do so.
thanks,

Hi Bhavesh,
I am no expert in this matter but typical Hive use cases don't involve updates.
If your workflow, relies considerably on updating existing data in Hive (i.e.
in HDFS), you might need to re-think your design or the tools you use.

I have spent a few days trying to get past what I feel is a trivial issue. Just
trying to commit Hive mapReduce results to a Cassandra CF using the Hive
overwrite table function. I have reviewed a few online examples and wrote my
procedure a few different ways, always getting the same exception.
Are you actually referring to RHive: https://github.com/nexr/RHive/wiki? If
so it looks like a very interesting project, but I haven't talked to anyone
actually using it yet. If it looks like a good fit for your particular
applications then the best thing would be to install and start working with
Sure -- use -hiveconf X=Y, which allows your script to reference ${hiveconf:X}

Hello,
Is it possible (and how) to pass parameters to hive scripts from command
line?
I would imagine something like:
hive -f xyz.sql -p date='2012-02-13'
which will substitute any occurrence of $date string in xyz.sql file.
I've searched wiki and list archive, but I didn't find any clues about

Hi all,
(cross posted to a few Hadoop mailing lists - apologies for the SPAM)
Are there any users around the Copenhagen area that would like a HUG meetup?
Just reply with +1 and I'll gauge interest. We could probably host a
1/2 or full day if people were coming from Sweden...
