Chip Sands commented on SPARK-4496:
-----------------------------------

I have not look at the spark code. But it would be in the code that send the result set to
thrift. My guess is a smallint is defined somewhere as and int (32 bit)
Hive does it correctly so maybe you can look there.

Just create a table with a smallint  datatype. 
Insert a row and select it back.

If you look at the packet trace you will see the getSchema, describes it correctly as the
smallint , but the  select returns the data in a 32 bit thrift value..
