Zheng Shao commented on HIVE-309:
---------------------------------
Hi Richard, sorry for the delay.
It seems the only call to registerUDF in your new patch is:
registerUDF(parts[2], clazz, operatorType, false);
This does not implement what you mentioned:
{code}
udf.IDENTIFIER=FUNCTIONNAME,CLASSNAME[,OPERATORTYPE,[ISOPERATOR,[DISPLAYNAME]]]
{code}
Does it?
> 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.
