Sharad Agarwal commented on MAPREDUCE-1048:
-------------------------------------------
Changes look good to me. Minor comments:
Would be better if we rename JobTracker#updateReservations to
JobTracker#incrReservations
In the jsp, all slot info should be together. We can move occupied/reserved
slot info after Nodes column
> Show total slot usage in cluster summary on jobtracker webui
