               Status: Patch Available  (was: Open)

New Enhancements for HADOOP on big clusters. 

I put some new commands into HADOOP based on 0.14.0 and modified some bugs especially in the
scheduling part. 


  1. Add Some commands to make it easy to monitor the cluster. 
      hhosts   -- Display hosts status in the cluster.
      hload     -- Display host load information including cpu usage, cpu usage and so on.
      hslot      --  Change host available slot to improve efficiency. 
      hopen   --  Enable a host on the fly.
      hclose  --  Disable a host on the fly
  2. Add Some commands to improve efficiency for a "Big Cluster"
      htop       -- Bring a job specified to the top prirority on the fly.
      hbot       -- Bring a job specified to the lowest priority on the fly.
      hjobkill  -- Kill a job
      hjobs    --  List job information in detailed format. 
  3. Enhance the task trunk dispatching method to make it more efficient when a job has many

  4. Improved job submitting efficiency asuring right priority
