Zheng Shao commented on HADOOP-4070:
------------------------------------
Can you add a test case, Tom?
For adding a test case, please add a "my.q" file in
hive/ql/src/test/queries/positive, and then run "ant test -Dtestcase=TestParse
-Dqfile=my.q", collect the standard result by searching for the failed "diff"
command in the test log.
And then do the same for hive/ql/src/test/queries/clientpositive, and "ant test
-Dtestcase=TestCliDriver -Dqfile=my.q".
Another thing is that do you think AdminWork will be responsible for other
works besides creating UDF? if not then let's call it a more specific name
(like CreateUDFWork).

> UDFs (user defined functions) in Hive are currently actually built-in
> functions. This issue is to develop a packaging and registration mechanism so
> users can add their own functions at runtime.
