Here, we see how to create a new instance of Curator. It takes the address of the ZooKeeper cluster and a RetryPolicy as arguments. While we are using the RetryOneTime policy in this book, this is probably not the right choice for production frameworks. Instead, the ExponentialBackoffRetry or BoundedExponentialBackoffRetry policies are more robust choices.

Note that you must explicitly start() the Curator framework.7

Next, we create a LeaderLatch for our framework, which we’ll put under the ZooKeeper path we chose for our framework, /sampleframework.
