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. 

Enhancements:

  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
tasks.

  4. Improved job submitting efficiency asuring right priority
