Laljo John Pullokkaran commented on HIVE-12644:
-----------------------------------------------
As we discussed, need to simplify the logic about limit overlaps (Top Limit &
Bottom Limit):
1. Fully contained
2. Partially contained
3. Outside
> Support for offset in HiveSortMergeRule

> Project: Hive
> Issue Type: Bug
> Components: CBO
> Affects Versions: 2.1.0
> Reporter: Jesus Camacho Rodriguez

>
> After HIVE-11531 goes in, HiveSortMergeRule needs to be extended to support
> offset properly when it merges operators that contain Limit. Otherwise, limit
> pushdown through outer join optimization (introduced in HIVE-11684) will not
> work properly.
