--------------------------------------------

Thanks, Bikas. Just trying to prevent Hadoop code from being contaminated with GPL or proprietary
code licenses. Sounds like you are already controlling for that.

> 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.
