Subject How dose zookeeper handle fault-detect in distributed storage system
Date Wed, 11 Sep 2013 06:17:15 GMT
Hi all:
	
	Recently my lab want to use zk to manager our cluster(Fault detect). Our cluster 
includes three kinds of node:
1. dispatch node : load balance and dispatch data.
2. store node: receive data from dispatch node and store.
3. middleware: query data from all the store node.
Here my question is : How dose zk handle fault-detect in this system(how dose dispatch node

and middleware know that a store node is down).
