As one other user, Tuong, suggested, it would be better to use cast in this following way:
select * from table1 where calldate in (
cast(    '2014-08-11' as date), cast('2014-05-02' as date));
This provides 2 benefits:
- correct semantic comparison for date values

- better performance as the cast is only done for the 2 literal values, not for every row
of calldate

Hi Kevin, 
I'm using 0.12 version and IN statement works fine except this
    situation:

select * from table1 where callhour in (1,2,3,4); --> success  
(callhour type: int)

select * from table1 where name in ('foo1','foo2','foo3','foo4');
    --> success
(name type: string)

select * from table1 where calldate = '2014-08-11'; --> success
(calldate type:date)

select * from table1 where calldate < '2014-08-11'; -->
    success
(calldate type:date)

select * from table1 where calldate in (
    '2014-08-11','2014-05-02');  -->error
(calldate type:date)

Error: Error while processing statement: FAILED: SemanticException
[Error 10014]: Line 1:38 Wrong arguments ''20014-03-02'': The
    arguments
for IN should be the same type! Types are: {date IN (string,
    string)}
(state=42000,code=10014)

if I use calldate with cast operator it works:
select * from table1 where cast(calldate as string) in (
    '2014-08-11','2014-05-02');

This is a relatively old stack overflow post. I’m not sure what version you guys are using,
but IN seems to work just fine for me.
