Subject [jira] [Commented] (YARN-3458) CPU resource monitoring in Windows
Date Tue, 07 Apr 2015 19:29:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-3458?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14483874#comment-14483874
] 

Inigo Goiri commented on YARN-3458:
-----------------------------------

For the tests, I checked the original TestWindowsBasedProcessTree and it didn't have related
to actually testing the resource monitoring; I'm open to suggestions.

Regarding the two warning, I'm not able to understand what this is complaining about; it says
that I have fields not accessed but the ones I added are referenced. I think ti refers to
Log but I'm not able to parse the error.

> The current implementation of getCpuUsagePercent() for WindowsBasedProcessTree is left
as unavailable. Attached a proposal of how to do it. I reused the CpuTimeTracker using 1 jiffy=1ms.
> This was left open by YARN-3122.
