------------------------------------

             Summary: Some INFO level logging needs to be DEBUG
                 Key: KAFKA-1592
                 URL: https://issues.apache.org/jira/browse/KAFKA-1592
             Project: Kafka
          Issue Type: Bug
            Reporter: Guozhang Wang
             Fix For: 0.9.0


Some of the INFO level log4j entries are not really useful, for example in 
SocketServer.Processor, due to metadata requests that reply on a separate and 
short-lived socket, the following log can be constantly printed:

info("Closing socket connection to 
%s.".format(channelFor(key).socket.getInetAddress)) 

We'd better move them to DEBUG if they are expected in normal state.
