             Summary: ERROR level log message should probably be changed to INFO
                 Key: HADOOP-8519
                 URL: https://issues.apache.org/jira/browse/HADOOP-8519
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 0.20.2
         Environment: Red Hat Enterprise Linux Server release 6.2 (Santiago)

            Reporter: Jeff Lord


Datanode service is logging java.net.SocketTimeoutException at ERROR level.
This message indicates that the datanode is not able to send data to the client 
because the client has stopped reading. This message is not really a cause for 
alarm and should be INFO level.
