[jira] [Created] (HBASE-14936) CombinedBlockCache should overwrite CacheStats#rollMetricsPeriod()

-----------------------------------

             Summary: CombinedBlockCache should overwrite CacheStats#rollMetricsPeriod()
                 Key: HBASE-14936
                 URL: https://issues.apache.org/jira/browse/HBASE-14936
             Project: HBase
          Issue Type: Bug
          Components: BlockCache
    Affects Versions: 1.1.2
            Reporter: Jianwei Cui


It seems CombinedBlockCache should overwrite CacheStats#rollMetricsPeriod() as
{code}
public void rollMetricsPeriod() {
  lruCacheStats.rollMetricsPeriod();
  bucketCacheStats.rollMetricsPeriod();
}
{code}
otherwise, CombinedBlockCache.getHitRatioPastNPeriods() and CombinedBlockCache.getHitCachingRatioPastNPeriods() will always return 0.
