Description

In order to implement HDFS-2671 (HDFS methods should throw StandbyException when in wrong state), we'd need to either add "throws StandbyException" to all of the protocol APIs, or make StandbyException extend from IOException. The latter is much simpler and less probability of it being a breaking change.
