Daniel Templeton commented on YARN-5913:
----------------------------------------
The issue at hand is that in {{ApplicationSubmissionContext}} {{resource}}
({{getResource()}}/{{setResource()}}) has the same meaning as
{{AMContainerResourceRequests}}
({{getAMContainerResourceRequests()}}/{{setAMContainerResourceRequests()}}).
Having two different properties that do the same thing is confusing. The task
here is to pick one and replace all calls to the other with it. I would
recommend replacing all uses of {{resource}} with
{{AMContainerResourceRequests}}. Then mark {{getResource()}} and
{{setResource()}} as deprecated.
There's one more issue. In YARN-2493 the patch strips the {{@Stable}} tag off
{{getResource()}} and {{setResource()}}. That's not OK. The {{@Stable}}
should be restored.
Let me know if you need more details.
