Jaimin D Jetly resolved AMBARI-12420.
-------------------------------------
Resolution: Duplicate
The DataNode code has been changed so that it would stop logging the
EOFException if a client connected to the data transfer port and immediately
closed before sending any data. This was achieved in HDFS-9572.
I am resolving this issue as duplicate.
