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

             Summary: support real time rpc invoke latency percentile statistics for methods of HRegionInterface 
                 Key: HBASE-10129
                 URL: https://issues.apache.org/jira/browse/HBASE-10129
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
    Affects Versions: 0.94.14
            Reporter: cuijianwei


It is important for applications to get latency statistics when invoking hbase apis. Currently, the average latency of methods in HRegionInterface will be computed in HBaseRpcMetrics. However, user might expect more detail latency statistics, such as 75% percentile latency, 95% percentile latency, etc. Therefore, will it be useful if we computing latency percentiles for rpc invoking of region server methods?
