dynamic map slots
Description
I have introduced process monitoring system inside tasktracker, which analyses the cpu and memory utilization of each map task and allows me to increase/decrease maximum number of map slots dynamically on each node. With this I can combine cpu intensive jobs along with memory intensive jobs, thereby reducing the cpu idle time.
