------------------------------------------

             Summary: Add an hdfs debug command to validate blocks, call recoverlease, etc.
                 Key: HDFS-6917
                 URL: https://issues.apache.org/jira/browse/HDFS-6917
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs-client
    Affects Versions: 2.6.0
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe


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.
