Task resource utilization reporting for profiling and scheduling
----------------------------------------------------------------
Key: MAPREDUCE-1195
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1195
Project: Hadoop Map/Reduce
Issue Type: New Feature
Reporter: Scott Chen
We can make TaskTracker reports its usage on CPU, memory, bandwidth to JobTracker. JobTracker
can use the information for scheduling tasks and profiling jobs.
One way to do this is to first make ProcfsProcessTree to collect the utilization information
(CPU, mem...) and write the information in TaskTrackerStatus.taskReports and send them with
the heartbeats. Then we can aggregate these information in JobInProgress to do job profiling
and scheduling.
