I thought that that the current thread context loader was the always the first loader to be tried anyway during name resolution. Yes, of course. the class loader holding by HiveConf is older than that of current thread. this pacth support dfs, add/delete file/jar, set now. btw, Joydeep, would you do me a favor writing some test code that I am not familiar with? you know, ' add jar' need a separate jar, and i not quite sure how to organize them. was (Author: coderplay): * exec/FunctionTask.java: is it necessary to specify the loader in the Class.forName call?

[jira] Created: (HIVE-556) let hive support theta join
let hive support theta join
---
Key: HIVE-556
URL: https://issues.apache.org/jira/browse/HIVE-556
Project: Hadoop Hive
Issue Type: New Feature
Affects Versions: 0.4.0
Reporter: Min Zhou
Fix For: 0.4.0
Right now , hive only support equal joins . Somethings it's not enough, we
must consider implementing theta joins like
{code:sql}
SELECT
a.subid, a.id, t.url
FROM
tbl t JOIN aux_tbl a ON t.url rlike a.url_pattern
WHERE
t.dt='20090609'
AND a.dt='20090609';
{code}
any condition expression following 'ON' is appropriate.
