I looked at the code.  I'm not familiar with this area of the code.

[~ashutoshc] [~jcamachorodriguez] [~vgarg] can you review ASAP.  Thanks.

review it or I can do it as long as some else looks at it later...

> Hi, 
> I based my DDL on this exemple https://fr.hortonworks.com/tutorial/using-hive-acid-transactions-to-insert-update-and-delete-data/.
> In a delete request, the use of a view in a subquery throw an exception : 
> FAILED: IllegalStateException Expected 'insert into table default.mydim select ROW__ID
from default.mydim sort by ROW__ID' to be in sub-query or set operation.
> {code}
> {code:sql}
> drop table if exists mydim;
> create table mydim (key int, name string, zip string, is_current boolean)
> clustered by(key) into 3 buckets
> stored as orc tblproperties ('transactional'='true');
> insert into mydim values
>   (1, 'bob',   '95136', true),
>   (2, 'joe',   '70068', true),
>   (3, 'steve', '22150', true);
> drop table if exists updates_staging_table;
> create table updates_staging_table (key int, newzip string);
> insert into updates_staging_table values (1, 87102), (3, 45220);
> drop view if exists updates_staging_view;
> create view updates_staging_view (key, newzip) as select key, newzip from updates_staging_table;
> delete from mydim
> where mydim.key in (select key from updates_staging_view);
> FAILED: IllegalStateException Expected 'insert into table default.mydim select ROW__ID
from default.mydim sort by ROW__ID' to be in sub-query or set operation.
