[jira] Commented: (MAPREDUCE-1048) Show total slot usage in cluster
summary on jobtracker webui
[ https://issues.apache.org/jira/browse/MAPREDUCE-1048?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12760867#action_12760867 ]
Amar Kamat commented on MAPREDUCE-1048:
---------------------------------------
In the cluster summary section on the jobtracker webui, map tasks/slots information would make more sense. Example
||Maps Tasks/Maps Slots||Reduces Tasks/Reduces Slots||Total Submissions||Nodes||Map Task Capacity||Reduce Task Capacity||Avg. Tasks/Node||Blacklisted Nodes||Excluded Nodes||
|10/30|38/76|55|38|228|76|8.00|0|0|

> With High-Ram jobs coming into the picture, its important to also show the slot usage in cluster summary since total-running-maps < total-slots-occupied.
