Xiaoyu Yao created HADOOP-12985:
-----------------------------------

             Summary: Support MetricsSource interface for DecayRpcScheduler Metrics
                 Key: HADOOP-12985
                 URL: https://issues.apache.org/jira/browse/HADOOP-12985

          Issue Type: Improvement
            Reporter: Xiaoyu Yao
            Assignee: Xiaoyu Yao


This allows metrics collector such as AMS to collect it with MetricsSink. The per user RPC call counts, schedule decisions and per priority response time will be useful to detect and trouble shoot Hadoop RPC server such as Namenode overload issues.
