Review comment:
It's a compatible issue. In normal case, data type is converted by Hive
ObjectInspector at running time. But Hive not support input decimal type when
method required double type. Unfortunately the default type of `1.1` is
different between Spark and Hive, which are decimal and double. Then caused
this issue.
