Description
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.
