Work Description: ZanderXu opened a new pull request, #4496:
URL: https://github.com/apache/hadoop/pull/4496
### Description of PR
In our prod environment, Observer NameNode also have high QueueTime, but
ProcessingTime is low.
After tracing and found the root cause is Rpc ReQueue.
So I thinks we should add a metric to quantify the number of reQueueRpc. And
It will be helpfully for us to locate this abnormal case.
