Folks, I am trying to set up a single node cluster for Hadoop ( version 1.0.1) on Ubuntu 11.04. After configuring everything, I could not get all the components to start.
My installation directory for hadoop is /usr/local/hadoop I followed the following tutorial for the setup : http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/ Below is the snapshot of my log file: mandeep@mandeep-System-Product-Name:/var/log/hadoop/mandeep$ cat hadoop-mandeep-datanode-mandeep-System-Product-Name.log 2012-04-29 01:29:37,240 INFO org.apache.hadoop.hdfs.server.datanode.DataNode: STARTUP_MSG: /************************************************************ STARTUP_MSG: Starting DataNode STARTUP_MSG: host = mandeep-System-Product-Name/127.0.1.1 STARTUP_MSG: args = [] STARTUP_MSG: version = 1.0.1 STARTUP_MSG: build = https://svn.apache.org/repos/asf/hadoop/common/branches/branch-1.0 -r 1243785; compiled by 'hortonfo' on Tue Feb 14 08:15:38 UTC 2012 ************************************************************/ 2012-04-29 01:29:37,398 INFO org.apache.hadoop.metrics2.impl.MetricsConfig: loaded properties from hadoop-metrics2.properties 2012-04-29 01:29:37,446 INFO org.apache.hadoop.metrics2.impl.MetricsSourceAdapter: MBean for source MetricsSystem,sub=Stats registered. 2012-04-29 01:29:37,449 INFO org.apache.hadoop.metrics2.impl.MetricsSystemImpl: Scheduled snapshot period at 10 second(s). 2012-04-29 01:29:37,449 INFO org.apache.hadoop.metrics2.impl.MetricsSystemImpl: DataNode metrics system started 2012-04-29 01:29:37,583 INFO org.apache.hadoop.metrics2.impl.MetricsSourceAdapter: MBean for source ugi registered. 2012-04-29 01:29:37,586 WARN org.apache.hadoop.metrics2.impl.MetricsSystemImpl: Source name ugi already exists! 2012-04-29 01:29:37,615 INFO org.apache.hadoop.util.NativeCodeLoader: Loaded the native-hadoop library 2012-04-29 01:29:37,701 ERROR org.apache.hadoop.hdfs.server.datanode.DataNode: java.lang.IllegalArgumentException: Does not contain a valid host:port authority: file:/// at org.apache.hadoop.net.NetUtils.createSocketAddr(NetUtils.java:162) at org.apache.hadoop.hdfs.server.namenode.NameNode.getAddress(NameNode.java:198) at org.apache.hadoop.hdfs.server.namenode.NameNode.getAddress(NameNode.java:228) at org.apache.hadoop.hdfs.server.namenode.NameNode.getServiceAddress(NameNode.java:222) at org.apache.hadoop.hdfs.server.datanode.DataNode.startDataNode(DataNode.java:337) at org.apache.hadoop.hdfs.server.datanode.DataNode.<init>(DataNode.java:299) at org.apache.hadoop.hdfs.server.datanode.DataNode.makeInstance(DataNode.java:1582) at org.apache.hadoop.hdfs.server.datanode.DataNode.instantiateDataNode(DataNode.java:1521) at org.apache.hadoop.hdfs.server.datanode.DataNode.createDataNode(DataNode.java:1539) at org.apache.hadoop.hdfs.server.datanode.DataNode.secureMain(DataNode.java:1665) at org.apache.hadoop.hdfs.server.datanode.DataNode.main(DataNode.java:1682) 2012-04-29 01:29:37,718 INFO org.apache.hadoop.hdfs.server.datanode.DataNode: SHUTDOWN_MSG: /************************************************************ SHUTDOWN_MSG: Shutting down DataNode at mandeep-System-Product-Name/ 127.0.1.1 ************************************************************/ 2012-04-29 01:33:26,907 INFO org.apache.hadoop.hdfs.server.datanode.DataNode: STARTUP_MSG: /************************************************************ -- Mandeep Singh Gulati System Analyst | WorldWide Risk and Information Management American Express India Pvt.
