Summary: RpcQueueTimeAvgTime of the NameNode increases after it

Key: HDFS-15727

Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs

Reporter: Aihua Xu

RpcQueueTimeAvgTime of the NameNode increases after it becomes StandBy. It will
get resolved after it gets restarted. Seems there is something incorrect about
this metrics.
See the following graph, the NameNode becomes StandBy at 10:13 while
RpcQueueTimeAvgTime increases instead.
