Currently, the hive parser will only accept a list of values in the where in clause and the filter is applied only on a single column. Enhanced it to accept filter on multiple columns.
So current support is for queries like :
Select * from table where c1 in (value1,value2,...value n);
Added support in the parser for queries like :
Select * from table where (c1,c2,... cn) in ((value1,value2...value n), (value1' , value2' ... ,value n').... )
Have added support for these queries in spark sql
