---------------------------------
Assignee: Sumit Mohanty
> Include node failure history when choosing placement hints
> ----------------------------------------------------------
>
> Key: SLIDER-743
> URL: https://issues.apache.org/jira/browse/SLIDER-743
> Project: Slider
> Issue Type: Improvement
> Components: appmaster
> Affects Versions: Slider 0.60
> Reporter: Steve Loughran
> Assignee: Sumit Mohanty
> Fix For: Slider 0.70
>
>
> Use the (collected) history on per-node failures to tune placement requests,
> so that even if there's a history of components running there, if its been
> failing recently then it's not asked for
> # Add a "recent failures" field to the node entries, alongside the "total
> failures" counter
> # the scheduled failure count resetter will set that field to zero,alongside
> the component failures
> # When Slider has to request a new container, if a node has a recent failure
> count above some threshold, it will not be requested, even if it is a past
> location of that component.
> When the placement policy is STRICT, node failure history will not be taken
> into account
