             Summary: Add a reQueue metric to RpcMetrics.java to quantify the number of RPCs in ReQueue
                 Key: HADOOP-18446
                 URL: https://issues.apache.org/jira/browse/HADOOP-18446
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: ZanderXu
            Assignee: ZanderXu


Add a reQueue metric to RpcMetrics.java to quantify the number of RPCs reQueued.

Because Observer NameNode will re-queue the rpc if the call processing should be postponed.

 

There is no any metric to quantify the number of re-queue RPCs, so I think we should do it.
