> HADOOP-10597 added support for RPC congestion control by sending retriable 'server too busy' exceptions to clients.
> However every backoff results in a log message. We've seen these log messages slow down the NameNode.
> {code}
> 2016-03-07 15:02:23,272 INFO org.apache.hadoop.ipc.Server: Socket Reader #1 for port 8020: readAndProcess from client 127.0.0.1 threw exception [org.apache.hadoop.ipc.RetriableException: Server is too busy.]
> {code}
> We already have a metric that tracks the number of backoff events. This log message adds nothing useful.
