> HDFS should have a debug command which could validate HDFS block files, call 
> recoverLease, and have some other functionality.  These commands would be 
> purely for debugging and would appear under a separate command hierarchy 
> inside the hdfs command.  There would be no guarantee of API stability for 
> these commands and the debug submenu would not be listed by just typing the 
> "hdfs" command.
