Wangda Tan updated YARN-6040:
-----------------------------
Attachment: YARN-6040.005.patch
Attached ver.5 patch addressed comments.
Now added API to get resourceName to make behavior not changed in
FSPreemptionThread.
bq. From your comment, it seems you are planning on moving canDelayTo() method
to a separate policy ? I was thinking the PlacementSet itself would encapsulate
the delay scheduling policy, but we can discuss that later.
Yeah I was thinking to make it as a part of SchedulingPlacementSet, but
implementation of delay policy could be independent and pluggable.
[~asuresh], mind to review again?

> As mentioned by YARN-5906, currently schedulers are using ResourceRequest
> heavily so it will be very hard to adopt the new PowerfulResourceRequest
> (YARN-4902).
> This JIRA is the 2nd step of refactoring, which remove usage of
> ResourceRequest from AppSchedulingInfo / SchedulerApplicationAttempt. Instead
> of returning ResourceRequest, it returns a lightweight and API-independent
> object - {{PendingAsk}}.
> The only remained ResourceRequest API of AppSchedulingInfo will be used by
> web service to get list of ResourceRequests.
> So after this patch, usage of ResourceRequest will be isolated inside
> AppSchedulingInfo, so it will be more flexible to update internal data
> structure and upgrade old ResourceRequest API to new.
