Why we have multiple hostnames for a single cluster

[Udara Liyanage <ud...@wso2.com>]

Hi,

According to the code, a cluster object's host names is a list. When there
can be multiple host names per a single cluster.
If someone wants to get the host name of LB cluster, which one to pick, is
it the first host name?

Hi Udara,

As you have mentioned, it will pick up the first hostname in the LB. I
found it from the below code segment:

String hostname = cluster.getHostNames().get(0);
        if (cluster.getHostNames().size() > 1) {
            if (log.isWarnEnabled()) {
                log.warn(String.format("Multiple hostnames found in cluster
%s, using %s",
                        cluster.getHostNames().toString(), hostname));
            }
        }

Thanks,
Reka
