[jira] [Created] (CARBONDATA-737) Add Map datatype support as Hive

Crabo Yang created CARBONDATA-737:
-------------------------------------

             Summary: Add Map datatype support as Hive
                 Key: CARBONDATA-737
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-737
             Project: CarbonData
          Issue Type: New Feature
            Reporter: Crabo Yang


Due to the lack of "alter ... add column ..." syntax support, we’re badly need a "Map datatype" in the complex types.

As Hive docs:
Maps

Maps in Hive are similar to Java Maps.
Syntax: MAP<primitive_type, data_type>
