Shuguang Liu updated HADOOP-2099:
---------------------------------

    Attachment: hadoop.0.14-pro.tgz

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
