Steve Loughran resolved SLIDER-967.
-----------------------------------
Resolution: Fixed
> Use nodemap to build up location restrictions on AA placement
> -------------------------------------------------------------
>
> Key: SLIDER-967
> URL: https://issues.apache.org/jira/browse/SLIDER-967
> Project: Slider
> Issue Type: Sub-task
> Components: appmaster
> Affects Versions: Slider 0.90
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Fix For: Slider 0.90
>
> Original Estimate: 8h
> Remaining Estimate: 8h
>
> This is the key AA placement work: AA placement requests to use nodemap to
> build up the explicit list of suitable nodes, while excluding
> # all nodes where there's an instance already
> # all nodes with an outstanding request
> # all nodes considered failed
> For now, let's include those considered "unreliable", as in having launches
> fail recently.
> The list to submit should be *all nodes with the target label expression*.
> This means that we'll have to use the label information in the nodemap and
> requests & do some matching in the AM first.
> Also: stop listing all the changed nodes on a nodemap update...just the
> first 10 should be enough.
