    Attachment: HIVE-15269.12.patch

Handle cycles due to map side joins and semi join combo.

> If a dimension table and fact table are joined:
> {noformat}
> select *
> from store join store_sales on (store.id = store_sales.store_id)
> where store.s_store_name = 'My Store'
> {noformat}
> One optimization that can be done is to get the min/max store id values that 
> come out of the scan/filter of the store table, and send this min/max value 
> (via Tez edge) to the task which is scanning the store_sales table.
> We can add a BETWEEN(min, max) predicate to the store_sales TableScan, where 
> this predicate can be pushed down to the storage handler (for example for ORC 
> formats). Pushing a min/max predicate to the ORC reader would allow us to 
> avoid having to entire whole row groups during the table scan.
