Examples of cacheForDAG()

org.apache.tez.runtime.api.ObjectRegistry.cacheForDAG()

Insert or update object into the registry with DAG life-cycle. This will remove an object associated with the same key with a different life-cycle as there is only one instance of an Object stored for a given key irrespective of the life-cycle attached to the Object. The object may stay in the cache while the DAG (to which the task belongs) is running. @param key Key to identify the Object @param value Object to be inserted @return Previous Object associated with the key attached if present elsenull. Could return the same object if the object was associated with the same key for a different life-cycle.

    testCRUD(objectRegistry);


    String one = "one";
    String two = "two";
    objectRegistry.cacheForVertex(one, one);
    objectRegistry.cacheForDAG(two, two);


    ((ObjectRegistryImpl)objectRegistry).clearCache(ObjectRegistryImpl.ObjectLifeCycle.VERTEX);
    Assert.assertNull(objectRegistry.get(one));
    Assert.assertNotNull(objectRegistry.get(two));

      if (userPayload != null) {
        boolean doLocalityCheck = getContext().getUserPayload().getPayload().get(0) > 0 ? true : false;
        if (doLocalityCheck) {
          ObjectRegistry objectRegistry = getContext().getObjectRegistry();
          String entry = String.valueOf(getContext().getTaskIndex());
          objectRegistry.cacheForDAG(entry, entry);
        }
