Description

The following case expression never evaluates to 'test1' when cdec is -1 or 10 as it will for Hive 0.13. Instead is returns 'other' for all rows.

select rnum, cdec, case when cdec in ( -1,10,0.1 )  then 'test1' else 'other' end from tdec 

create table  if not exists TDEC ( RNUM int , CDEC decimal(7, 2 )    )
TERMINATED BY '\n'
