      Description

      Link: https://drill.apache.org/docs/hive-to-drill-data-type-mapping/

      It says CHAR is supported and LIST, MAP, STRUCT, TIMESTAMP (Unix Epoch format), UNION are not supported.

      While querying a table with char datatype field, Drill client says:

      Unsupported Hive data type CHAR.
      Following Hive data types are supported in Drill INFORMATION_SCHEMA:
      BOOLEAN, BYTE, SHORT, INT, LONG, FLOAT, DOUBLE, DATE, TIMESTAMP,
      BINARY, DECIMAL, STRING, VARCHAR, LIST, MAP, STRUCT and UNION

      This is really confusing. Please look into this.
