Scott Chen updated MAPREDUCE-1167:
----------------------------------
Attachment: MAPREDUCE-1167-v3.patch
1. Rename rssmem to rssmemPage to help clarify.
2. Throws Exception when PAGESIZE is not available.
@Vinod: After reviewing the code, I think it is better to use page number in
ProcessInfo because ProcessInfo is simply a parsed version of /proc/PID
directory. It should be consistent with what's in /proc. I changed the field's
name from rssmem to rssmemPage and also the getters' names. I think this should
be able to help clarify. Also ProcessInfo is a private class. I think as long
as our public methods all use bytes it should be fine.
> Make ProcfsBasedProcessTree collect rss memory information
