Jonathan Hung commented on YARN-7584:
-------------------------------------
In addition, right now the assumption is components will only request
cpu/memory resources. I think it also makes sense to allow fine-grained
resource requests for other resources, e.g. allow specifying "gpu": 1 in the
"resources" json object, otherwise the only way to specify non-cpu/memory
resources are through resource profiles, which seems inflexible.

> Currently resource profiles does not appear to be supported: {noformat} //
> Currently resource profile is not supported yet, so we will raise
> // validation error if only resource profile is specified
> if (StringUtils.isNotEmpty(resource.getProfile())) {
> throw new IllegalArgumentException(
> RestApiErrorMessages.ERROR_RESOURCE_PROFILE_NOT_SUPPORTED_YET);
> }{noformat}
> Also attempting to specify profiles in the service spec throws an exception
> since cpu default value is 1:
> {noformat}Exception in thread "main" java.lang.IllegalArgumentException:
> Cannot specify cpus/memory along with profile for component ps
