      Description

      Proposal 1:
      If a include files is used, then show all nodes (dead/alive) that are listed in the includes file. If there isn't an include file, then display only nodes that have pinged this instance of the namenode.

      Proposal2:
      A config variable specifies the time duration. The namenode, on a restart, purges all datanodes that have not pinged for that time duration. The default value of this config variable can be 1 week.
