nandan updated MAPREDUCE-2653:
------------------------------
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. (was: I have introduced process
monitoring system in hadoop 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)
Environment: linux
Affects Version/s: 0.20.203.0
Tags: dynamic map slots
Labels: map scheduler tasks (was: )
Remaining Estimate: 672h
Original Estimate: 672h
> dynamic map slots (in addition to predifined) on each node which allows to
> execute cpu intensive jobs along with memory intensive jobs thereby reducing
> wastage of cpu cycles
