----------------------------------

[~templedf] , 

Thanks for posting your comments, 

I agree with your 2/3/4, and for 1, I still prefer server instead of the client 
since it's better to make sure a given profile means the same across 
apps/clients in the same cluster.

Since I will be off in the next few weeks, I will try to get a draft patch 
ready by today or tomorrow and talked to [~sunilg] offline, [~sunilg] will help 
this.

> 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?
