> Key: HADOOP-19109
> URL: https://issues.apache.org/jira/browse/HADOOP-19109

> This description of the RpcLockWaitTimeNumOps metrics seems to be incorrect：
> {code:java}
> | `RpcQueueTimeNumOps` | Total number of RPC calls |
> | `RpcQueueTimeAvgTime` | Average queue time in milliseconds |
> | `RpcLockWaitTimeNumOps` | Total number of RPC calls (same as RpcQueueTimeNumOps) |{code}
> I think the description of this metrics should be more clear：
> {code:java}
> | `RpcLockWaitTimeNumOps` | Total number of waiting for lock acquisition |{code}
