Bikas Saha commented on MAPREDUCE-4203:
---------------------------------------
Sorry, I should have been more clear. winutils is a native executable that gets
built on Windows. The source for that got added in HADOOP-8235. It provides key
functionality like permissions, groups, hard links etc that are required to run
Hadoop on Windows. This patch adds more support by adding functionality to
winutils to monitor memory etc for tasks.
> Create equivalent of ProcfsBasedProcessTree for Windows

> 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.
