[jira] Created: (HDFS-1568) Improve DataXceiver error logging

Improve DataXceiver error logging
---------------------------------

                 Key: HDFS-1568
                 URL: https://issues.apache.org/jira/browse/HDFS-1568
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: data-node
    Affects Versions: 0.23.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
            Priority: Minor


In supporting customers we often see things like SocketTimeoutExceptions or EOFExceptions coming from DataXceiver, but the logging isn't very good. For example, if we get an IOE while setting up a connection to the downstream mirror in writeBlock, the IP of the downstream mirror isn't logged on the DN side.
