Project: Hadoop HDFS
Issue Type: Bug
Components: namenode

Dead code after JDK 1.4
{code}
otherHttpAddr = DFSUtil.getInfoServerWithDefaultHost(
otherIpcAddr.getHostName(), otherNode, scheme).toURL();
{code}
In {{DFSUtil#substituteForWildcardAddress}}
{code}
if (addr != null && addr.isAnyLocalAddress()) {
...

addr.isAnyLocalAddress() will always return false.
Always the url will be formed with address which is configured in
hdfs-site.xml .Same will affect bootStrap from NN and ssl certificate check
