org.springframework.yarn.fs.SmartResourceLocalizer

{@code SmartResourceLocalizer} provides additional functionality ontop of {@link ResourceLocalizer} order to handle more fine grainedhandling of resource localizing.

These smart functionalities includes of controlling localizing process manually, copy files into file system prior the localization and use staging concept of application files.

Logic of having methods for manually resolving, distributing and copying resources is to have an early possibility to fail fast if something goes wrong. Although one need to remember that on all circumstances calling {@link ResourceLocalizer#getResources()}should always be enough. @author Janne Valkealahti @see ResourceLocalizer

    // localizer distribute will kick off too early
    ApplicationId applicationId = clientRmOperations.getNewApplication().getApplicationId();
    log.info("submitApplication, got applicationId=[" + applicationId + "]");


    if (resourceLocalizer instanceof SmartResourceLocalizer) {
      SmartResourceLocalizer smartResourceLocalizer = (SmartResourceLocalizer)resourceLocalizer;
      smartResourceLocalizer.setStagingId(applicationId.toString());
      if (!distribute) {
        smartResourceLocalizer.resolve();
      } else {
        smartResourceLocalizer.distribute();
      }
    } else {
      log.warn("Resource localizer is not instance of SmartResourceLocalizer, thus we're unable to resolve and distrute manually");
    }
