Yan Xu updated MESOS-6219:
--------------------------
Summary: Improve auto-detection of predefined resource types. (was:
Improve auto-detection of built-in resources)
> Improve auto-detection of predefined resource types.
> ----------------------------------------------------
>
> Key: MESOS-6219
> URL: https://issues.apache.org/jira/browse/MESOS-6219
> Project: Mesos
> Issue Type: Improvement
> Components: containerization
> Reporter: Yan Xu
>
> Mesos agent currently auto-detects certain standard resources when they are
> not specified. These include cpus, mem, (root) disk, gpus and also MESOS-6062
> is adding auto-detection for mount disks when the size is specified as a
> special value "0".
> Due to the limitation of the {{Resources}} abstraction the caller of
> {{Resources::parse()}} can't tell if a resource is intentionally specified
> with an empty value or unspecified. The current resource auto-detection in
> {{Containerizer::resources()}} resorts to scanning the {{--resources}} flag
> to check if resource is specified, this is very fragile, e.g., it would think
> {{gpus:0}} is specified (ant not auto-detected) if there is a mount disk with
> its root being {{/biggpush}}.
> It would be nice if we can have the user explicitly specify the intention to
> have value of a standard resource auto-detected (at least with the JSON
> input).
