Description

For this SQL, which should disable Storage limit push. Because this SQL will return more than one record from HBase tables, but the SortedIteratorMergerWithLimit only return one record, which will get wrong result.

SELECT sum(A) 
FROM TABLE 
WHERE date_id >= 20170624 and date_id <= 20170626 
limit 1

We should disable Storage limit push down when singleValuesD doesn't containsAll othersD
