Allow HDFS DataNodes and NameNode to have different build versions
------------------------------------------------------------------

                 Key: HDFS-1129
                 URL: https://issues.apache.org/jira/browse/HDFS-1129
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: dhruba borthakur


There are times when we want to deploy fixes to the NameNode without restarting the DataNodes.
This reduces the restart time of the entire cluster.
