Subject [jira] [Created] (HBASE-17393) Logic in TimeRange#includesTimeRange is incorrect
Date Fri, 30 Dec 2016 01:02:38 GMT
huaxiang sun created HBASE-17393:
------------------------------------

             Summary: Logic in TimeRange#includesTimeRange is incorrect
                 Key: HBASE-17393
                 URL: https://issues.apache.org/jira/browse/HBASE-17393
             Project: HBase
          Issue Type: Bug
          Components: regionserver
            Reporter: huaxiang sun
            Assignee: huaxiang sun
            Priority: Minor


In the code,

https://github.com/apache/hbase/blob/master/hbase-common/src/main/java/org/apache/hadoop/hbase/io/TimeRange.java#L181
 
return getMin() < tr.getMax() && getMax() >= tr.getMin();

Given that TimeRange is defined as [minStamp,maxStamp), 

Assume that TimeRange(4, 5). includesTimeRange(TimeRange(5,6)).
So it will be (4 < 6) && (5 >=5), the result is true.

Same for TimeRangeTracker#includesTimeRange
