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..
> smallint (16 bit value) is being send as a 32 bit value in the thrift
> interface.
