Richard Lee updated HIVE-309:
-----------------------------
Attachment: hive-external-functions2.diff
Finally got a unit test working with loading UDFs via property files. The test
verifies that both UDF and UDAF mappings are picked up.
It seems like the classpath situation with junit/ant is a little different than
regular execution... so the hive-udf.properties needed to be copied into the
build directory where the unit tests are run from.
> FunctionRegistry should allow loading UDFs and UDAFs from property file

> FunctionRegistry.java hard code all UDF, UDAF definitions in a static
> initializer. There is no way to add new functions without directly modifying
> this file.
> FunctionRegistry SHOULD look for a property file in which new functions and
> their implementations can be specified. This will allow third parties to
> extend hive without maintaining patches against the codebase.
