Steve Loughran commented on SLIDER-490:
---------------------------------------
you are right ... it should be looking at outstanding requests first.
I don't think there's any support in slider for cancelling outstanding requests
(yet), but we could still not overreact to a flex down.
this should be testable in the mock rm
> When containers ask cannot be satisfied, flex down seems to bring down active
> containers

> URL: https://issues.apache.org/jira/browse/SLIDER-490
> Project: Slider
> Issue Type: Bug
> Components: appmaster
> Affects Versions: Slider 0.50
> Reporter: Sumit Mohanty
> Assignee: Steve Loughran
>
> Noticed that if a component is flexed up and there are no resources to
> satisfy the requests they remain unsatisfied by YARN. This is expected.
> However, if the component is flexed down then the live containers are brought
> down instead of just counting them against the unsatisfied requests.
