> Attempting to group by tiny ints is considered okay by the CLI, but there's a run time error on the server side giving:
> java.lang.RuntimeException: org.apache.hadoop.hive.serde2.SerDeException: org.apache.hadoop.hive.serde2.dynamic_type.ParseException: Encountered "byte" at line 1, column 32.
> Was expecting one of:
> "bool" ...
> "i16" ...
> "i32" ...
> "i64" ...
> "double" ...
> "string" ...
> "map" ...
> "list" ...
