Subject [jira] [Created] (CARBONDATA-737) Add Map datatype support as Hive
Date Thu, 02 Mar 2017 02:11:46 GMT
Crabo Yang created CARBONDATA-737:

             Summary: Add Map datatype support as Hive
                 Key: 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 in Hive are similar to Java Maps.
Syntax: MAP<primitive_type, data_type>
