Subject [jira] Created: (MAPREDUCE-1167) Make ProcfsBasedProcessTree collect rss memory information
Date Thu, 29 Oct 2009 19:43:59 GMT
Make ProcfsBasedProcessTree collect rss memory information
----------------------------------------------------------

                 Key: MAPREDUCE-1167
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1167
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
          Components: tasktracker
    Affects Versions: 0.20.1
            Reporter: Scott Chen


Right now ProcfsBasedProcess collects only virtual memory. We can make it collect rss memory
as well.
Later we can use rss in TaskMemoryManagerThread to obtain better memory management.
