             Summary: Need metrics of cache hit ratio for one table
                 Key: HBASE-15643
                 URL: https://issues.apache.org/jira/browse/HBASE-15643
             Project: HBase
          Issue Type: Bug
            Reporter: Heng Chen


There are many tables on our cluster,  we  only some of them need to be read 
online.  

We could improve the performance of read by cache,  but we need some metrics 
for it at table level
