> HS2 NULL_TYPE should be implemented using TStringValue.
> [https://github.com/apache/impala/blob/master/common/thrift/hive-1-api/TCLIService.thrift#L327]
> However, due to incompatibility with Hive JDBC driver implementation then, Impala choose to implement NULL type using TBoolValue (see IMPALA-914, IMPALA-1370).
> The Hive JDBC issue is not there anymore. Thus, we can reimplement NULL_TYPE using TStringValue to match HiveServer2 behavior.
