Yes. If we are to provide unit tests, we must be aware of the network
interfaces in the host machine.I manually tested whether all are fine when I
wanted to run a zookeeper cluster to test my clustering implementation through
a LAN and it worked fine.
```
List<InstanceSpec> specs = new ArrayList<>();
List<Integer> ports = new ArrayList<>();
int port = 30155, electionPort = 31155, quorumPort = 32155;
for (int i = 0; i < 3; i++) {
InstanceSpec spec = new InstanceSpec(null, port, electionPort,
quorumPort,
true, i, 10000, 100, null, "0.0.0.0");
logger.info("Zookeeper-{} : port : {}, election port : {},
quorum port : {}", i, port, electionPort, quorumPort);
specs.add(spec);
ports.add(port);
port++;
electionPort++;
quorumPort++;
}
logger.info("Connect string ports : {}", ports);
TestingCluster cluster = new TestingCluster(specs);
try {
cluster.start();
Runtime.getRuntime().addShutdownHook(new Thread(() -> {
try {
logger.debug("Stopping cluster");
cluster.stop();
} catch (IOException e) {
logger.error("Error when stopping cluster", e);
}
}));
} catch (Exception e) {
logger.error("Error when starting zookeeper cluster", e);
throw e;
}
logger.info("Cluster started with ports : {}", ports);
```
Here, I had used "0.0.0.0" to open ports on all interfaces. I tried with my
IPv4 address assigned by my LAN and confirmed that I can access these ports
through network
