> Improve FS docs
> ---------------
>
> Key: YARN-381
> URL: https://issues.apache.org/jira/browse/YARN-381
> Project: Hadoop YARN
> Issue Type: Improvement
> Affects Versions: 2.0.0-alpha
> Reporter: Eli Collins
> Assignee: Sandy Ryza
> Priority: Minor
>
> The MR2 FS docs could use some improvements.
> Configuration:
> - sizebasedweight - what is the "size" here? Total memory usage?
> Pool properties:
> - minResources - what does min amount of aggregate memory mean given that
> this is not a reservation?
> - maxResources - is this a hard limit?
> - weight: How is this ratio configured? Eg base is 1 and all weights are
> relative to that?
> - schedulingMode - what is the default? Is fifo pure fifo, eg waits until all
> tasks for the job are finished before launching the next job?
> There's no mention of ACLs, even though they're supported. See the CS docs
> for comparison.
> Also there are a couple typos worth fixing while we're at it, eg "finish.
> apps to run"
> Worth keeping in mind that some of these will need to be updated to reflect
> that resource calculators are now pluggable.
