on reconnect, DN can connect to NN even with different source versions
----------------------------------------------------------------------

                 Key: HDFS-2120
                 URL: https://issues.apache.org/jira/browse/HDFS-2120
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: John George
            Assignee: John George


DN or NN does not check for source versions in cases when NN goes away or has lost connection.
The only check that is done by NN is for LAYOUT_VERSION and DN does not check for any version
mismatch.
