Linux zookeeper
From John Freier
ZooKeeper is a cluster operator that stores values to be shared across multiply clients.
Shell Commands
The server works by using things called znodes, kind of like a file system /
This shell is very helpful for debugging issue and understand what Zoo Keeper does under the hood.
To Start the shell
./zkCli.sh -server localhost:2181
ls - list out the directory create /test - creates the znode test get /test - gets the data for the znode
Spring Cloud ZooKeeper
This framework helps manage the clients that connect to zookeeper. You can also use this for sharing values amongst a cluster.
