Examples with ApplicationInitedEvent org.apache.hadoop.yarn.server.nodemanager.containermanager.application.ApplicationInitedEvent used on opensource projects

Example 1 with ApplicationInitedEvent

use of org.apache.hadoop.yarn.server.nodemanager.containermanager.application.ApplicationInitedEvent in project hadoop by apache.

the class ResourceLocalizationService method handleInitApplicationResources.

/**
   * Handle event received the first time any container is scheduled
   * by a given application.
   */
@SuppressWarnings("unchecked")
private void handleInitApplicationResources(Application app) {
    // 0) Create application tracking structs
    String userName = app.getUser();
    privateRsrc.putIfAbsent(userName, new LocalResourcesTrackerImpl(userName, null, dispatcher, true, super.getConfig(), stateStore));
    String appIdStr = app.getAppId().toString();
    appRsrc.putIfAbsent(appIdStr, new LocalResourcesTrackerImpl(app.getUser(), app.getAppId(), dispatcher, false, super.getConfig(), stateStore));
    // 1) Signal container init
    //
    // This is handled by the ApplicationImpl state machine and allows
    // containers to proceed with launching.
    dispatcher.getEventHandler().handle(new ApplicationInitedEvent(app.getAppId()));
