case insensitive string equality

[Amlan Mandal]

(Please pardon my ignorance as I am Hive newbie)

When I do Hive QL
select * from app_log where partner='abc';
and
select * from app_log where partner='ABC'

I get different result. That means by default Hive string equality is case
sensitive . Is there any GLOBAL/Hive wide setting so that string equality is
case insensitive?
