> As Preston Koprivica pointed out at the tail of HBASE-4394, when all filters
> in a MUST_PASS_ONE FilterList return a SEEK_USING_NEXT_HINT code, we should
> return SEEK_NEXT_USING_HINT from the FilterList to utilize the lowest seek
> value.
> This would save unnecessary accesses to blocks which are not in scan result.
> A unit test has been added which shows the reduction in the number of blocks
> accessed when this optimization takes effect.
