Whenever I try to start the DFS, I get this error: had...@namenode:~/hadoop-0.19.1$ bin/start-dfs.sh starting namenode, logging to /home/hadoop/hadoop-0.19.1/bin/../logs/hadoop-hadoop-namenode-hadoop-namenode.out 10.31.253.142: starting datanode, logging to /home/hadoop/hadoop-0.19.1/bin/../logs/hadoop-hadoop-datanode-hadoop-slave-a.out 10.31.253.146: starting datanode, logging to /home/hadoop/hadoop-0.19.1/bin/../logs/hadoop-hadoop-datanode-hadoop-slave-b.out 10.31.253.135: starting secondarynamenode, logging to /home/hadoop/hadoop-0.19.1/bin/../logs/hadoop-hadoop-secondarynamenode-hadoop-jobtracker.out 10.31.253.130: starting secondarynamenode, logging to /home/hadoop/hadoop-0.19.1/bin/../logs/hadoop-hadoop-secondarynamenode-hadoop-namenode.out 10.31.253.135: Exception in thread "main" java.lang.NullPointerException 10.31.253.135: at org.apache.hadoop.net.NetUtils.createSocketAddr(NetUtils.java:132) 10.31.253.135: at org.apache.hadoop.hdfs.server.namenode.NameNode.getAddress(NameNode.java:130) 10.31.253.135: at org.apache.hadoop.hdfs.server.namenode.NameNode.getAddress(NameNode.java:134) 10.31.253.135: at org.apache.hadoop.hdfs.server.namenode.SecondaryNameNode.initialize(SecondaryNameNode.java:131) 10.31.253.135: at org.apache.hadoop.hdfs.server.namenode.SecondaryNameNode.<init>(SecondaryNameNode.java:115) 10.31.253.135: at org.apache.hadoop.hdfs.server.namenode.SecondaryNameNode.main(SecondaryNameNode.java:469)
What could be the problem? 10.31.253.130 is the namenode 10.31.253.135 is the job tracker
