Namenode.initialize() sets the default filesystem uri to an ip6 address (0:0:0:0:0:0:0:0)
-----------------------------------------------------------------------------------------

                 Key: HADOOP-3395
                 URL: https://issues.apache.org/jira/browse/HADOOP-3395
             Project: Hadoop Core
          Issue Type: Bug
          Components: fs
    Affects Versions: 0.17.0
            Reporter: Clint Morgan


When starting the namenode, I would get the following exception:

Caused by: java.io.IOException: Incomplete HDFS URI, no host/port: hdfs://0:0:0:0:0:0:0:0:50051
	at org.apache.hadoop.dfs.DistributedFileSystem.initialize(DistributedFileSystem.java:66)
	at org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:1275)
	at org.apache.hadoop.fs.FileSystem.access$300(FileSystem.java:56)
	at org.apache.hadoop.fs.FileSystem$Cache.get(FileSystem.java:1286)

	at org.apache.hadoop.dfs.NameNode.<init>(NameNode.java:180)
	at org.apache.hadoop.dfs.NameNode.<init>(NameNode.java:166)


I tracked this down to NameNode.java line 127 and 128. The socetAddress returned by this.server.getListenerAddress() is an ipv6 style address with colons. Then this is set as the default filesystem which causes problems on the next call to FileSystem.get.

I replacedthe line:
this.nameNodeAddress = this.server.getListenerAddress();
with
this.nameNodeAddress = socAddr;

And this made it work for me. However, I gather this would break support  for ephemeral ports? Is there a better way for me to fix this, maybe disabling ipv6 elsewhere?
