INSERT INTO with named field list and CBO=false fails

Queries that insert into tables using a named field list fail when CBO is disabled.

Here's an example to illustrate what I mean:

INSERT INTO dd_insert_values_test(field1, field2) VALUES ('hive.cbo.enable=false', 'With named fields');

Notice that it names the fields (field1, field2) into which the values should be inserted.

With CBO disabled this query fails with error:

– Error: Error while compiling statement: FAILED: SemanticException 0:0 Expected 2 columns for insclause-0/daved@dd_insert_values_test; select produces 1 columns. Error encountered near token ''With named fields'' (state=42000,code=40000)

With CBO enabled it works.

And without the named field list, it works with either CBO enabled or disabled. Please see the attached repro script: INSERT INTO with named field list and CBO=false bug.txt
