Ted Yu updated HBASE-15243:
---------------------------
Attachment: HBASE-15243-v4.txt
Patch v4 adds a test.
Without the optimization in FilterList, the test would fail with:
{code}
estMultiRowRangeWithFilterListOrOperatorWithBlkCnt(org.apache.hadoop.hbase.filter.TestFilterListOrOperatorWithBlkCnt)
Time elapsed: 255.387 sec <<< FAILURE!
java.lang.AssertionError: expected:<4> but was:<8>

org.apache.hadoop.hbase.filter.TestFilterListOrOperatorWithBlkCnt.testMultiRowRangeWithFilterListOrOperatorWithBlkCnt(TestFilterListOrOperatorWithBlkCnt.java:112)
{code}
> Utilize the lowest seek value when all Filters in MUST_PASS_ONE FilterList
> return SEEK_NEXT_USING_HINT

> 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.
