      Description

      From the design doc:

      This command is useful while decommissioning a server. It removes the specified server (hostname:port) as favored node from regions. This operation does not change any assignments, but alters favored node information in hbase:meta. The users have to make sure that the specified server is not hosting any regions. Since region servers go down much more frequently than datanodes, the admin has to use this tool when decommissioning a datanode and region server.
