![]() ![]() Here’s an example that uses port 2184 for a three-node ZooKeeper cluster:ĬlientPort = 2184 server.1 = :2185:2186 server.2 = :2185:2186 server.3 = :2185:2186Īs before, create the myid files for each server on data/global-zookeeper/myid. To deploy a ZooKeeper configuration store in a single-cluster instance, add the same ZooKeeper servers used by the local quorom to the configuration file in conf/global_nf using the same method for local ZooKeeper, but make sure to use a different port (2181 is the default for ZooKeeper). If your Pulsar instance will consist of just one cluster, then you can deploy a configuration store on the same machines as the local ZooKeeper quorum but running on different TCP ports. If, however, you’re deploying a multi-cluster instance, then you should stand up a separate ZooKeeper cluster for configuration tasks. If you’re deploying a single-cluster instance, then you will not need a separate cluster for the configuration store. In addition to a local cluster, however, a full Pulsar instance also requires a configuration store for handling some instance-level configuration and coordination tasks. The ZooKeeper cluster configured and started up in the section above is a local ZooKeeper cluster used to manage a single Pulsar cluster. Here’s an example for a three-node cluster: Add a server.N line for each node in the cluster to the configuration, where N is the number of the ZooKeeper node. To begin, add all ZooKeeper servers to the quorum configuration specified in the conf/nf file. ZooKeeper manages a variety of essential coordination- and configuration-related tasks for Pulsar.ĭeploying a Pulsar instance requires you to stand up one local ZooKeeper cluster per Pulsar cluster. The global ZooKeeper quorum can be provided by an independent cluster of machines or by the same machines used by local ZooKeeper. Global ZooKeeper operates at the instance level and provides configuration management for the entire system (and thus across clusters).Each Pulsar cluster needs to have a dedicated ZooKeeper cluster. Local ZooKeeper operates at the cluster level and provides cluster-specific configuration management and coordination.ZooKeeperĮach Pulsar instance relies on two separate ZooKeeper quorums. Skip to the How Pulsar uses ZooKeeper and BookKeeper section below for a more schematic explanation of the role of these two systems in Pulsar. ![]()
