Scott Chen updated MAPREDUCE-220:
---------------------------------
Attachment: MAPREDUCE-220.txt
This patch implements the feature that transmit the per task CPU and memory
information through TaskTracker heartbeat.
Here's a summary of the changes:
1. Add three methods in LinuxResourceCalculatorPlugin to get the cumulative CPU
time, physical memory and virtual memory of a process (aggregated all the
subprocesses)..
2. Add a method called resourceStatusUpdate in TaskTracker to update the
resource status in TaskStatus.taskReports before sending heartbeat.
3. Add a nested class called ResourceStatus in TaskStatus to store the CPU and
memory information.
3. Modify TestTTResource to check if the per task resource information actually
transmitted.
