---------------------------------------
Assignee: Nishant Goel
> INSERT INTO with named field list and CBO=false fails
> -----------------------------------------------------
>
> Key: HIVE-22991
> URL: https://issues.apache.org/jira/browse/HIVE-22991
> Project: Hive
> Issue Type: Bug
> Components: Query Planning
> Affects Versions: 3.0.0
> Reporter: David Doran
> Assignee: Nishant Goel
> Priority: Minor
> Attachments: INSERT INTO with named field list and CBO=false bug.txt
>
>
> 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]
