Arun C Murthy commented on YARN-2817:
-------------------------------------
Kafka on YARN (KAFKA-1754) would benefit enormously if it could reserve a
certain number of drives on a node exclusively.
> Disk as a resource in YARN
> --------------------------
>
> Key: YARN-2817
> URL: https://issues.apache.org/jira/browse/YARN-2817
> Project: Hadoop YARN
> Issue Type: New Feature
> Components: scheduler
> Reporter: Arun C Murthy
> Assignee: Arun C Murthy
>
> As YARN continues to cover new ground in terms of new workloads, disk is
> becoming a very important resource to govern.
> It might be prudent to start with something very simple - allow applications
> to request entire drives (e.g. 2 drives out of the 12 available on a node),
> we can then also add support for specific iops, bandwidth etc.
