Harsh J resolved HADOOP-3395.
-----------------------------
Resolution: Duplicate
While you're supposed to use hostnames for HDFS URIs, HADOOP-6056 fixes this
issue by shipping with the IPv4 preferrer opt. Resolving as dupe.
> 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 Common
> 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.fs.FileSystem.get(FileSystem.java:208)
> at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:108)

> 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?
