Min Zhou commented on HIVE-521:
-------------------------------
I didn't think all tests would pass due to the shortage of a class
BinaryComparable. The reason why failing has nothing to do with this jira. you
can check out the trunk,and do
ant -Dhadoop.version=0.17.0 test -Doverwrite=true
then error message will be displayed.

> Move size, if, isnull, isnotnull to GenericUDF

> Key: HIVE-521

> See HIVE-511 for an example of the move.
> size, if, isnull, isnotnull are all implemented with UDF but they are
> actually working on variable types of objects. We should move them to
> GenericUDF for better type handling.
> This also helps to clean up the hack in doing type matching/type conversion
> in UDF.
