### Step 3: Test on RabbitMQ

The python program below waits on the queue exchange `bucketevents` and prints event notifications on the console. We use [Pika Python Client](https://www.rabbitmq.com/tutorials/tutorial-three-python.html) library to do this.

```py
#!/usr/bin/env python

            }
        } catch (final Exception e) {
            logger.warn("Failed to create {} mapping.", configIndex, e);
        }
    }

    /**
     * Waits for the search engine cluster to reach yellow or green status.
     *
     * @param fessConfig the Fess configuration
     * @throws ContainerInitFailureException if the cluster doesn't become available
     */

   * computes or retrieves it using the supplied {@code CacheLoader}. If another thread is currently
   * loading the value for this key, simply waits for that thread to finish and returns its loaded
   * value. Note that multiple threads can concurrently load values for distinct keys.

    val logs = testLogHandler.takeAll()

    // While MockWebServer waits to read the client's HEADERS frame before sending the response, it
    // doesn't wait to read the client's DATA frame and may send a DATA frame before the client
    // does. So we can't assume the client's empty DATA will be logged first.

ts feature gate. It can be used to tell kubeadm to wait for all control plane components to be ready when running "kubeadm init" or "kubeadm join --control-plane". Currently kubeadm only waits for the kube-apiserver. The "kubeadm join" workflow now includes a new experimental phase called "wait-control-plane". This phase will be marked as non-experimental when WaitForAllControlPlaneComponents becomes GA. Accordingly a "kubeadm init" phase "wait-control-plane" will also be available once WaitForA...

  * Minimum CPU limits is 10m. This is a Linux Kernel limitation
  * “kubectl rollout undo” (i.e. rollback) will hang on paused deployments, because
paused deployments can’t be rolled back (this is expected), and the command
waits for rollback events to return the result. Users should use “kubectl
rollout resume” to resume a deployment before rolling back.
  * “kubectl edit <list>” will open the editor multiple times, once for each
resource in the list.
