String host1 = "hoang.ngo.org:41414";
String host2 = "hoang.ngo.org:41414";
String host3 = " hoang.ngo.org:41414";
props.put("hosts.h1", host1);
props.put("hosts.h2", host2);
props.put("hosts.h3", host3);
props.put("host-selector", "random"); // For random host selection
// props.put("host-selector", "round_robin"); // For round-robin host
// // selection
props.put("backoff", "true"); // Disabled by default.

props.put("maxBackoff", "10000"); // Defaults 0, which effectively
