[jira] [Created] (FLINK-27374) Convert Hive's void type to Flink's string type

luoyuxia created FLINK-27374:
--------------------------------

             Summary: Convert Hive's void type to Flink's string type
                 Key: FLINK-27374
                 URL: https://issues.apache.org/jira/browse/FLINK-27374
             Project: Flink
          Issue Type: Improvement
            Reporter: luoyuxia


Currently, we don't support Hive's void type. But some Hive's udf call will return void type such as nvl(null, null), then it'll throw 'Flink doesn't support Hive primitive type void yet'. 

For Hive's void type, we can convert it to Flink's string type internally to avoid such case.
