Karthik Kambatla commented on YARN-2141:
----------------------------------------
I would like to look at YARN-2141 as a pre-requisite of YARN-1012. Once we
capture the actual resource consumption, we can use it in multiple ways - (1)
Send to the RM, (2) Log it for debugging etc.
> [Umbrella] Capture container and node resource consumption
> ----------------------------------------------------------
>
> Key: YARN-2141
> URL: https://issues.apache.org/jira/browse/YARN-2141
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: nodemanager
> Reporter: Carlo Curino
> Priority: Minor
>
> Collecting per-container and per-node resource consumption statistics in a
> fairly granular manner, and making them available to both infrastructure code
> (e.g., schedulers) and users (e.g., AMs or directly users via webapps), can
> facilitate several performance work.
