      Description

      When SMP is enabled, the RM starts with the following fatal message:

      FATAL event.AsyncDispatcher (AsyncDispatcher.java:dispatch(189)) - Error in dispatcher thread true
      java.lang.Exception: No handler for registered for class org.apache.hadoop.yarn.server.resourcemanager.metrics.AbstractSystemMetricsPubli
      sher$SystemMetricsEventType
             at org.apache.hadoop.yarn.event.AsyncDispatcher.dispatch(AsyncDispatcher.java:185)
             at org.apache.hadoop.yarn.event.AsyncDispatcher$1.run(AsyncDispatcher.java:109)
             at java.lang.Thread.run(Thread.java:745)
      

      We should register event handlers in service init stage in TimelineServiceV2Publisher to fix this problem.
