[GitHub] [hadoop] ZanderXu commented on pull request #4660: HDFS-16703. Enable RPC Timeout for some protocols of NameNode.

   @slfan1989 Sir, about this PR, if you thinks it's difficult to configure it, how about just enabling a configurable timeout for NamenodeProtocolPB? 
   
   Because we encountered many times this problem in our prod environment that RBF can not sense the crashed namenode in time, because the `NamenodeHeartbeatService` are blocked to waiting for the response from namenode for a long time.
