[jira] [Created] (HIVE-19672) Column Names mismatch between native Druid Tables and Hive External map

slim bouguerra created HIVE-19672:
-------------------------------------

             Summary: Column Names mismatch between native Druid Tables and Hive External map
                 Key: HIVE-19672
                 URL: https://issues.apache.org/jira/browse/HIVE-19672
             Project: Hive
          Issue Type: Bug
          Components: Druid integration
    Affects Versions: 3.0.0
            Reporter: slim bouguerra
             Fix For: 4.0.0


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.
