-Hadoop now requires Java 6.
+Changed command "hadoop dfsadmin -report" to be consistent with Web UI for both Namenode and Datanode reports. "Total raw bytes" is changed to "Configured Capacity". "Present Capacity" is newly added to indicate the present capacity of the DFS. "Remaining raw bytes" is changed to "DFS Remaining". "Used raw bytes" is changed to "DFS Used".
