Steve Loughran updated SLIDER-84:
---------------------------------
Sprint: slider may 2
> switch from thread-based container launch to Futures
> ----------------------------------------------------
>
> Key: SLIDER-84
> URL: https://issues.apache.org/jira/browse/SLIDER-84
> Project: Slider
> Issue Type: Improvement
> Components: appmaster
> Affects Versions: Slider 0.30
> Reporter: Steve Loughran
> Priority: Minor
> Original Estimate: 2h
> Remaining Estimate: 2h
>
> The role launching code in the AM is based off Distributed Shell: uses a
> thread per launched container. This will have scale limits when launching a
> very large cluster if the assignments all come in near-simultaneously.
> Switching to a Java futures model would allow the AM to deploy via an
> executor that limited the number of operations active; possibly also support
> a better shutdown
