Description

~~HADOOP-12985~~ introduced a few metrics2 counters for DecayRpcScheduler. The counters should be initialized before the updater thread is created/executed. Otherwise, this is a chance of NPE if the updater thread get executed before the counters are fully initialized. I will post a patch for it shortly.
