      New mradmin command -refreshNodes updates the job tracker's node lists.

    Description

      Its not always possible to shutdown the tasktracker to stop scheduling tasks on the node. (eg you can't login to the node but the TT is up).

      This can be via

      • mapred.exclude and should be refreshed with out restarting the tasktracker
      • hadoop job -fail-tracker <tracker id>
