-----------------------------------
Resolution: Fixed
> RoleHistory to (carefully) share RoleStatus instances with AppState
> -------------------------------------------------------------------
>
> Key: SLIDER-965
> URL: https://issues.apache.org/jira/browse/SLIDER-965
> Project: Slider
> Issue Type: Sub-task
> Components: appmaster
> Affects Versions: Slider 0.90
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Fix For: Slider 0.90
>
>
> Move the {{RoleHistory}} beyond simple read-time {{ProviderRole}}
> information, to sharing the map of RoleStatus entries with {{AppState}}.
> This involves improving the concurrency of the class. The plan is to move all
> integer counters in {{RoleState}} into the atomic {{LongGauge}} fields, with
> some downcoversion to integers at the last moment possible.
