I have a multi-node cluster with two datanodes. After running start-dfs.sh, I show the following processes running
hadoop@hadoop-master:~$ $HADOOP_HOME/sbin/slaves.sh jps hadoop-master: 10933 DataNode hadoop-master: 10759 NameNode hadoop-master: 11145 SecondaryNameNode hadoop-master: 11567 Jps hadoop-data1: 5186 Jps hadoop-data1: 5059 DataNode hadoop-data2: 5180 Jps hadoop-data2: 5053 DataNode However, the other two DataNodes aren't visible. http://screencast.com/t/icsLnXXDk Where can I look for clues?
