Cluster environment, seemed to add compiler environment,

If your configuration file is set up, you can start a ZooKeeper server:
$Java - cp zookeeper. Jar: lib/log4j - 1.2.15. Jar: the conf \ org apache. Zookeeper. Server. Quorum. QuorumPeerMain zoo. The CFG
QuorumPeerMain starts a ZooKeeper server, JMX management beans are also registered which allows management through a JMX management console. The ZooKeeper JMX document contains details on managing ZooKeeper with JMX.
See the script bin/zkServer. Sh, which is included in the release, for an example of starting server instances.
