> hive> alter table zzzzz add partition (i='2012-01-01', j='foo');          
> FAILED: SemanticException [Error 10248]: Cannot add partition column j of type string
as it cannot be converted to type date
> hive> alter table zzzzz add partition (i='2012-01-01', j=date 'foo');
> OK

> hive> select * from zzzzz where j == date 'foo';
> FAILED: SemanticException Unable to convert date literal string to date value.
