Main components (ex: CatalogServer, TajoResourceTracker) create an
InetSocketAddress with NetUtils::createSocketAddr and TajoConf. But if the
address set to "0.0.0.0" at TajoConf, NetUtils::createSocketAddr bind socket
address to "localhost" unconditionally. It does matter on Yarn with TajoMaster
Ha. If socket address bind to "localohost" in Netty, TajoWorker never can't
connect the component. So, I set local ip address with
NetUtils::createLocalSocketAddr. If you have any good idea, suggest to me
easefully.
