Daniel Templeton commented on YARN-7292:
----------------------------------------

Hang on.  If I understand that correctly, you're saying that in order to not 
have the profile overridden, the app developer has to create their own 
AMRMClient implementation?  Doesn't that mean that profiles will always be 
overridden in all practical cases, e.g. MR, Spark, Hive, etc.?

> 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?
