Strongly recommend using JStorm's Nimbus HA Design. It is pretty stable. JStorm's Nimbus HA has been released for one year and has been approved stable. The logic is very simple. The code less 1000 lines. 1. Every nimbus will try to own the znode /nimbus_master, the winner will be the nimbus's master. Slaves will watch and timely check the znode, once it disappear, slaves will try to own it. During slaves check the znode, it will sync binary from master. 2. All client API firstly connection ZK and get to know who are the nimbus Master. (1) The core code in nimbus: https://github.com/alibaba/jstorm/blob/master/jstorm-server/src/main/java/com/alibaba/jstorm/schedule/FollowerRunnable.java (2) How to find the master of nimbus: https://github.com/alibaba/jstorm/blob/master/jstorm-client/src/main/java/backtype/storm/security/auth/ThriftClient.java
