Subject [jira] [Updated] (HBASE-15243) Utilize the lowest seek value when all Filters in MUST_PASS_ONE FilterList return SEEK_NEXT_USING_HINT
Date Sat, 20 Feb 2016 02:32:18 GMT

     [ https://issues.apache.org/jira/browse/HBASE-15243?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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>
	at org.junit.Assert.fail(Assert.java:88)
	at org.junit.Assert.failNotEquals(Assert.java:834)
	at org.junit.Assert.assertEquals(Assert.java:645)
	at org.junit.Assert.assertEquals(Assert.java:631)
	at org.apache.hadoop.hbase.filter.TestFilterListOrOperatorWithBlkCnt.testMultiRowRangeWithFilterListOrOperatorWithBlkCnt(TestFilterListOrOperatorWithBlkCnt.java:112)
{code}

> 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.
