After configuring the geo-replication on Pulsar clusters, the clusters list
API will return multiple clusters, including the local Pulsar cluster and remote clusters like
bin/pulsar-admin clusters list us-west us-east us-cent
But in this return, you can't distinguish the local and the remote cluster. When you need to remove the geo-replication configuration, it will be hard to decide which cluster should be removed on replicated tenants and namespaces unless you record the cluster information.
Add --current
option to the cluster list cmd and mark the current cluster with (*)
bin/pulsar-admin clusters list --current us-west(*) us-east us-cent
Add --current
option to the cluster list cmd
@Parameter(names = { "-c", "--current" }, description = "Print the current cluster with (*)", required = false) private boolean current = false;
void run() throws PulsarAdminException { java.util.List<String> clusters = getAdmin().clusters().getClusters(); String clusterName = getAdmin().brokers().getRuntimeConfigurations().get("clusterName"); List<String> result = clusters.stream().map(c ->c.equals(clusterName) ? (current ? c + "(*)" : c) : c).collect(Collectors.toList()); print(result); }
