Details

    Description

      The current error when applying column masking over (unsupported) complex data types could be improved and be more explicit.

      Currently, the thrown error is as follows:

      Caused by: java.lang.RuntimeException: org.apache.hadoop.hive.ql.parse.SemanticException:org.apache.hadoop.hive.ql.parse.ParseException: line 1:57 cannot recognize input near 'map' '<' 'string' in primitive type specification
