[jira] Updated: (HADOOP-2123) Enhancements and Improvement for Host
monitor in a big cluster
[ https://issues.apache.org/jira/browse/HADOOP-2123?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Shuguang Liu updated HADOOP-2123:
---------------------------------
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
