             Summary: Mutable range histogram reports incorrect outliers
                 Key: HBASE-22045
                 URL: https://issues.apache.org/jira/browse/HBASE-22045
             Project: HBase
          Issue Type: Bug
    Affects Versions: 2.1.3, 1.4.9, 2.0.0, 1.3.3, 1.5.0, 3.0.0, 2.2.1

MutableRangeHistogram during the snapshot calculates the outliers (eg. mutate_TimeRange_600000-inf) and adds the counter with incorrect calculation by using the overall count of event and not the number of events in the snapshot.
{code:java}
    long val = histogram.getCount();
    if (val - cumNum > 0) {
      metricsRecordBuilder.addCounter(
          Interns.info(name + "_" + rangeType + "_" + ranges[ranges.length - 1] + "-inf", desc),
          val - cumNum);
    }{code}
