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.fs.Trash.<init>(Trash.java:62) > at org.apache.hadoop.dfs.NameNode.initialize(NameNode.java:138) > 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? -- This message is automatically generated by JIRA.
