         Environment: Red Hat Enterprise Linux Server release 6.2 (Santiago)

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.
