This is code that accompanies a talk I gave on Apache ZooKeeper. The slides can be found at http://www.slideshare.net/scottleber/apache-zookeeper May 2017 Update: * Updated ZooKeeper version to 3.4.10 * Updated Curator version to 2.12.0 * Changed all System.out to SLFJ Loggers * A bunch of misc. code cleanup, e.g. converting anonymous inner classes to lambdas, using diamond operator, etc.
