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.
