[jira] [Commented] (MAPREDUCE-4203) Create equivalent of ProcfsBasedProcessTree for Windows

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4203?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13393560#comment-13393560 ] 

Jonathan Eagles commented on MAPREDUCE-4203:
--------------------------------------------

Bikas, when you say based on winutils, it makes me think you are basing this patch on some existing code. If so, can you comment on the source and licensing.

> 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.
