Phil Yang commented on HBASE-15484:
-----------------------------------
I find that KeyValueHeap.peak() just returns next Cell in current scanner,
doesn't pass to QueryMatcher or filters. So moreCellsInRow logic in HRegion can
not make sure we must have more. So parital(hasMoreCellsInRow) flag in Result
is actually "mayHasMoreCellsInRow". If it is true, the result may still be the
last Result for a row, and if it is false the result must be the last.
> Correct the semantic of batch and partial

> Follow-up to HBASE-15325, as discussed, the meaning of setBatch and
> setAllowPartialResults should not be same. We should not regard setBatch as
> setAllowPartialResults.
> And isPartial should be define accurately.
> (Considering getBatch==MaxInt if we don't setBatch.) If
> result.rawcells.length<scan.getBatch && result is not the last part of this
> row, isPartial==true, otherwise isPartial == false. So if user don't
> setAllowPartialResults(true), isPartial should always be false.
