Hi all, I'm trying to set up a small cluster with 3 machines. I'd like to have one machine serves as the namenode and the jobtracker, while the 3 all serve as the datanode and tasktrackers.
After following the set up instructions, I got an exception running $HADOOP_HOME/bin/start-dfs.sh: java.net.BindException:Address already in use and my secondarynamenode cannot be started. But as I can see, the namenode started and the three data nodes all started. Does this matter? However, when I go to the webinterface at localhost:50070, I saw there is 1 datanode. Is there any reason why the data nodes are not started on the other two machines? The site.xml file and the java path, installation path etc are all set up. Does anyone have this problem before? I 'd really appreciate any help! Thanks!
