[HIVE-19672] Column Names mismatch between native Druid Tables and Hive External table map

• Type: Bug

Description

Druid Columns names are case sensitive while Hive is case insensitive.
This implies that any Druid Datasource that has columns with some upper cases as part of column name it will not return the expected results.
One possible fix is to try to remap the column names before issuing Json Query to Druid.
