Review comment:
```
public static String getDefaultHost(@Nullable String strInterface,
@Nullable String nameserver, boolean tryfallbackResolution) throws
UnknownHostException {
if (strInterface != null && !"default".equals(strInterface)) {
if (nameserver != null && "default".equals(nameserver)) {
nameserver = null;
}
String[] hosts = getHosts(strInterface, nameserver,
tryfallbackResolution);
return hosts[0];
} else {
return cachedHostname;
}
```
It cached in DNS.java(class in hadoop-common) yet.
