-------------------------------------
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>
