Laljo John Pullokkaran commented on HIVE-11684:
-----------------------------------------------
We should allow users to turn off any optimization CBO or NO-CBO.
Also we have to enhance the logic in CBO to find out if individual
optimizations doesn't make sense and turn it off automatically. Turning off
join ordering optimizations if no of joins is 1 is a good example.
> Implement limit pushdown through outer join in CBO
