Ivan Mitic commented on MAPREDUCE-4203:
---------------------------------------
bq. ProcessInfo.age initializes to 1. So newpInfo.age += oldpInfo.age does what
you say apart from allowing newpInfo to have a different age too.
I see. It seems that they are over-incrementing the value in
{{ProcfsBasedProcessTree}} as the default value is also one.
bq. The main calling function will do that with the return code of this
function.
I could not find this...would you mind checking?
Thanks!

> ProcfsBasedProcessTree is used by the TaskTracker to get process information
> like memory and cpu usage. This information is used to manage resources etc.
> The current implementation is based on Linux procfs functionality and hence
> does not work on other platforms, specifically windows.
