      Description

      Currently, the standby NN will log StandbyExceptions at ERROR level any time a client tries to connect to it. So, if the second NN in an HA pair is active, the first NN will spew a lot of these errors in the log, as each client gets redirected to the proper NN. Instead, this should be at INFO level, and should probably be logged in a less "scary" manner (eg "Received READ request from client 1.2.3.4, but in Standby state. Redirecting client to other NameNode.")
