Hey All, I am trying to install hadoop 0.20.2 and proceeded till daemon-start-up bin/start-all.sh. But I see no datanode created.
jps output: 43323 JobTracker 43281 SecondaryNameNode 43162 NameNode 43403 Jps 43381 TaskTracker 19747 Named node log: 2011-01-31 15:08:47,343 INFO org.apache.hadoop.ipc.Server: IPC Server handler 6 on 9000, call addBlock(/tmp/hadoop-sjagannath/mapred/system/ jobtracker.info, DFSClient_-462680310) from 127.0.0.1:61167: error: java.io.IOException: File /tmp/hadoop-sjagannath/mapred/system/ jobtracker.info could only be replicated to 0 nodes, instead of 1 java.io.IOException: File /tmp/hadoop-sjagannath/mapred/system/ jobtracker.info could only be replicated to 0 nodes, instead of 1 at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.getAdditionalBlock(FSNamesystem.java:1271) at org.apache.hadoop.hdfs.server.namenode.NameNode.addBlock(NameNode.java:422) at sun.reflect.GeneratedMethodAccessor8.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:508) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:959) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:955) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:396) at org.apache.hadoop.ipc.Server$Handler.run(Server.java:953) I am sure, I am doing what ever the quickstarts asks me to do. I am following: a. http://hadoop-tutorial.blogspot.com/2010/11/running-hadoop-in-pseudo-distributed.html b. http://hadoop.apache.org/common/docs/current/single_node_setup.html I am no sure what is going on. I would love to clear this hurdle and get my hand dirty with the actual work. Please let me know what is happening. Thanks, Sharath
