             Summary: RegionServerMetricsWrapperRunnable will be failure  when disable blockcache.
                 Key: HBASE-15976
                 URL: https://issues.apache.org/jira/browse/HBASE-15976

          Issue Type: Bug
    Affects Versions: 0.98.15
            Reporter: Liu Junhong


When i disable blockcache, the code "cacheStats = blockCache.getStats();" will occur NPE in org.apache.hadoop.hbase.regionserver.MetricsRegionServerWrapperImpl.RegionServerMetricsWrapperRunnable.
It lead to many regionserver's metrics' value always equal 0.
