spark sql in-clause problem

[onmstester onmstester]

I'm reading from this table in cassandra:

Table mytable (
Integer Key,

Integer X,

Interger Y



Using:

sparkSqlContext.sql(select * from mytable where key = 1 and (X,Y) in 
((1,2),(3,4)))



Encountered error: 



StructType(StructField((X,IntegerType,true),StructField((Y,IntegerType,true)) 
!= 
StructType(StructField((X,IntegerType,false),StructField((Y,IntegerType,false))
