> While doing tests, there're a couple of issues:
> 1) When use {{ProfileCapability#getProfileCapabilityOverride}}, it does
> overwrite of whatever specified in resource-profiles.json when value >= 0.
> Which is different from javadocs of {{ProfileCapability}}
> bq. For example, if you have a resource profile "small" that maps to <4096M,
> 2 cores, 1 gpu> and you set the capability override to <8192M, 0 cores, 0
> gpu>, then the actual resource allocation on the ResourceManager will be
> <8192M, 2 cores, 1 gpu>
> To me, the correct behavior should do overwrite when value > 0. The reason
> is, by default resource value will be set to 0, For example, assume we have a
> profile {{"a" = (mem=3, vcore=5, res_1=7)}}, and create a
> capability-overwrite (capability = new resource(8). The final result should
> be (mem=8, vcore=5, res_1=7), instead of (mem=8, vcore=0, res_1=0).
> 2) ResourceProfileManager now loads minimum/maximum profile from config file
> (resource-profiles.json), to me this is not correct because minimum/maximum
> allocation for each resource types are already specified inside
> {{resource-types.xml}}. We should always use
> {{ResourceUtils#getResourceTypesMinimum/MaximumAllocation}} to get from
> resource-types.xml and yarn-site.xml. This value will be added to profiles so
> client can get these configs.
