| /** |
| * Class to capture capability requirements when using resource profiles. The |
| * ProfileCapability is meant to be used as part of the ResourceRequest. A |
| * profile capability has two pieces - the resource profile name and the |
| * overrides. The resource profile specifies the name of the resource profile |
| * to be used and the capability override is the overrides desired on specific |
| * resource types. |
| * |
| * For example, if you have a resource profile "small" that maps to |
| * {@literal <4096M, 2 cores, 1 gpu>} and you set the capability override to |
| * {@literal <8192M, 0 cores, 0 gpu>}, then the actual resource allocation on |
| * the ResourceManager will be {@literal <8192M, 2 cores, 1 gpu>}. |
| * |
| * Note that the conversion from the ProfileCapability to the Resource class |
| * with the actual resource requirements will be done by the ResourceManager, |
| * which has the actual profile to Resource mapping. |
