Subject Datanodes not connecting to the cluster
Date Thu, 24 Sep 2015 17:51:04 GMT
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.

Where can I look for clues?
