----------------------------------------------
[~leftnoteasy]:
bq. I can understand your proposal may look different from my guess above, we
can discuss more once you have a more concrete design for that.
Yes, let's discuss about service planning once we add more details in the
design document -- it will be easier for other people to get involved in the
discussion too.
bq. I'm not care too much about if we should support cardinality via GUTS API
or support anti-affinity via cardinality syntaxes. We should choose a more
generic/extensible API which can support both.
Sounds good, we can continue the discussion in YARN-5478.

> Apache Hadoop YARN's ResourceRequest mechanism is the core part of the YARN's
> scheduling API for applications to use. The ResourceRequest mechanism is a
> powerful API for applications (specifically ApplicationMasters) to indicate
> to YARN what size of containers are needed, and where in the cluster etc.
> However a host of new feature requirements are making the API increasingly
> more and more complex and difficult to understand by users and making it very
> complicated to implement within the code-base.
> This JIRA aims to generalize and unify all such scheduling-strategies in YARN.
