> After some investigation, we found out that 1.2 based deployments will
> consistently face this problem under the following conditions:
> 1) The sum of all KVs size targeted to be returned in the scan is larger than
> *max result size*;
> 2) At same time, the scan filter has exhaust, so that all remaining KVs
> should be filtered and not returned;
> We could simulate this with the UT being proposed in this PR. When checking
> newer branches, though, I could verify this specific problem is not present
> on newer branches, I believe it was indirectly sorted by changes from
> HBASE-17489.
> Nevertheless, I think it would still be useful to have this extra test and
> checks added as a safeguard measure.
