I would take a look into how hive could possibly integrate with zoo-keeper and/or cascading.I know cascading just added the capability of working with hbase it its model.

Hi Joydeep, How can I use Hive's java api to operate data sets stored in Hive? Could you give me a simple example? Thanks Min -- My research interests are distributed systems, parallel computing and bytecode based virtual machine. http://coderplay.javaeye.com

One way to interact with hive is by starting hives thrift server. If you want to use the raw java API, I stole some code from the Command Line Interface and made a simple driver program. (I attached it). You could also take a look at the source hwi folder. That is how we have multiple hive client

Okay, so our people here looked at this further. In the Hadoop source, the exception is thrown every time the constructor is called so it means nothing. We're in a crunch to get this up and running today and would really appreciate some help: *The console hangs with any query that causes a map/re

Hi Huan, I guess this problem is caused by incompatibility between hadoop 0.17.0 and 0.18.3. Please ignore my previous comments about compiling hive against 0.17.0 and use it on 0.18.3 then. Can you try this? *ant clean ant -Dtarget.dir=/hive -Dhadoop.version='0.18.3' package * I took a deeper l

Hi Zheng, thank you for the speedy response! Yes! that is exactly the problem/answer to that problem... After ant clean, and rebuild, it ran without exceptions. Later it hung while we ran a query that went to map reduce... After some inspection, it was discovered that our hadoop cluster had a rac

My bad. I meant that use Hive's java API to do raw mapreduce things, not drive a sql. Sorry! On Wed, Feb 25, 2009 at 12:05 AM, Edward Capriolo wrote: > One way to interact with hive is by starting hives thrift server. If > you want to use the raw java API, I stole some code from the Command > L

Please take a look at: http://wiki.apache.org/hadoop/Hive/LanguageManual/Transform You will have to create a string command and pass it to Hive. There is no way of doing that directly (without creating a string) using Java API. Zheng On Tue, Feb 24, 2009 at 5:12 PM, Min Zhou wrote: > My bad.

We can write a small example program to get files for a table/partition. To open a table using deserializer and get rows from it etc. This would help people write java map-reduce on hive tables. From: Zheng Shao [mailto:zsh...@gmail.com] Sent: Tuesday, February 2

Ok, just for posterity, I seemed to have gotten this working now. It seems that specifying it in jpox.properties does not work. That is strange since when I run it with verbose output, it says that it found jpox.properties but I guess it doesn't use the values set there. hive-default.xml will work,

I think config values in hive-default.xml override the ones in jpox.properties so if you had stale or incorrect props in hive-default but correct ones in jpox.properties then it would be a problem. From: Ryan Shih Reply-To: Date: Tue, 24 Feb 2009 18:35:10 -080
