Steve Loughran updated SLIDER-82:
---------------------------------
Issue Type: Improvement (was: Sub-task)
Parent: (was: SLIDER-69)
> Support ANTI_AFFINITY_REQUIRED option
> -------------------------------------
>
> Key: SLIDER-82
> URL: https://issues.apache.org/jira/browse/SLIDER-82
> Project: Slider
> Issue Type: Improvement
> Components: appmaster
> Reporter: Steve Loughran
>
> slider has an anti-affinity flag in roles (visible in resources.json?), which
> is ignored.
> YARN-1042 promises this for YARN, slider will need
> # flag in resources.json
> # use in container requests
> we may also want two policies: anti-affinity-desired, and -required. Then if
> required nodes get >1 container for the same component type on the same node,
> it'd have to request a new one and return the old one (Risk: getting the same
> one back).
