Daniel Templeton commented on YARN-7292:
----------------------------------------
I these are still relevant questions and something I'd like to sort out for
3.1. My thoughts:
1) I could go either way on the client v/s server, but I think it's more useful
to have on the client side. It makes the code significantly simpler on the
server side and allows users to define their own profiles.
2) No, no, and no. They're redundant with what's already specified by resource
types.
3) Same question as #1. I vote for client side.
4) If we're supporting server-side profiles, overrides are required in order
for the profiles to be useful. If we're going with client-side profiles, then
overrides are moot.
> Revisit Resource Profile Behavior
> ---------------------------------
>
> Key: YARN-7292
> URL: https://issues.apache.org/jira/browse/YARN-7292
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: nodemanager, resourcemanager
> Reporter: Wangda Tan
> Assignee: Wangda Tan
> Priority: Blocker
>
> Had discussions with [~templedf], [~vvasudev], [~sunilg] offline. There're a
> couple of resource profile related behaviors might need to be updated:
> 1) Configure resource profile in server side or client side:
> Currently resource profile can be only configured centrally:
> - Advantages:
> A given resource profile has a the same meaning in the cluster. It won’t
> change when we run different apps in different configurations. A job can run
> under Amazon’s G2.8X can also run on YARN with G2.8X profile. A side benefit
> is YARN scheduler can potentially do better bin packing.
> - Disadvantages:
> Hard for applications to add their own resource profiles.
> 2) Do we really need mandatory resource profiles such as
> minimum/maximum/default?
> 3) Should we send resource profile name inside ResourceRequest, or should
> client/AM translate it to resource and set it to the existing resource
> fields?
> 4) Related to above, should we allow resource overrides or client/AM should
> send final resource to RM?
