Hive endpoint is empty

Error message

Hive endpoint is empty

What it means

parseEndpoint validates each endpoint string: after trimming whitespace it must be non-empty. An empty value cannot be split into host/port, so the driver returns this error immediately. It usually surfaces when an endpoint list contains blank entries.

Solutions

1. Remove empty entries from the endpoints/hosts list before parsing
2. Set the host value in the parameter or environment variable that feeds parseEndpoint
3. Filter/split host lists carefully (e.g. strings.Fields or a filtering split on ',')

Example fix

// before
hosts := strings.Split(env_hosts, ",") // may contain ""
// after
var hosts []string
for _, h := range strings.Split(env_hosts, ",") {
    if strings.TrimSpace(h) != "" { hosts = append(hosts, h) }
}

if strings.TrimSpace(endpoint) == "" {
    return errors.New("refusing to parse empty endpoint")
}

ep, err := parseEndpoint(value, defaultPort)
if err != nil {
    return fmt.Errorf("endpoint %q invalid: %w", value, err)
}

When it happens

Trigger: Passing "" or a whitespace-only string to parseEndpoint (directly or via a hosts/endpoints parameter that contains empty items, e.g. 'host1:10000,,host2' or a trailing comma).

Common situations: Environment variable with a trailing/leading comma producing an empty split item; config file with an empty hosts field; splitting a host list on the wrong delimiter.
