Description

Similar to YARN-7383, when parsing mapreduce configs for resource values, right now the regex omits dots. (See

  public static List<ResourceInformation> getRequestedResourcesFromConfig(
      Configuration configuration, String prefix) {
    List<ResourceInformation> result = new ArrayList<>();
    Map<String, String> customResourcesMap = configuration
        .getValByRegex("^" + Pattern.quote(prefix) + "[^.]+$");

in ResourceUtils.java)

Since YARN-7442 introduces a regex for resource names, we can use that to find mapreduce resource configs.
