             Summary: Creating a materialized view with no tables should be handled more gracefully
                 Key: HIVE-22209
                 URL: https://issues.apache.org/jira/browse/HIVE-22209
             Project: Hive
          Issue Type: Bug
          Components: Materialized views
            Reporter: Jesus Camacho Rodriguez
            Assignee: John Sherman


Currently, materialized views without a table reference are not supported. However, instead of printing a clear message about it, when a materialized view is created without a table reference, we fail with an unclear message.

{code}
> create materialized view mv_test1 as select 5;
(...)
