> Key: HADOOP-2123
> URL: https://issues.apache.org/jira/browse/HADOOP-2123
> Project: Hadoop
> Issue Type: Improvement
> Components: dfs, mapred
> Affects Versions: 0.14.0
> Reporter: Shuguang Liu
> Fix For: 0.14.1

> 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
