      Description

      Consider this message:

      org.apache.hadoop.ipc.RemoteException(java.io.IOException): File somefile could only be replicated to 0 nodes instead of minReplication (=1). There are 1 datanode(s) running and no node(s) are excluded in this operation.

      Obviously a node was excluded but not in the sense that the Datanode treats it. Considering that this is a message that noobs will see a lot, making it clearer will be a win.
