Vineet Garg updated HIVE-15673:
-------------------------------
    Attachment: HIVE-15673.1.patch

This patch is to test if CALCITE-1546 works. Since this patch updates the 
calcite version to a snapshot version this is not committable.

> Allow multiple queries with disjunction

> HIVE currently doesn't allow multiple subqueries with {{OR}} since calcite 
> has a bug in determining logic for OR expression. See [CALCITE-1546 
> |https://issues.apache.org/jira/browse/CALCITE-1546].
> Once calcite is released containing fix for the bug HIVE will need to lift 
> the restriction and add tests cases
