Hi, I am new to Hadoop. I just downloaded release 0.14.4 (hadoop-0.14.4.tar.gz) and trying to setup Hadoop on Single Machine (RedHat Linux 9) by following the link http://www.michael-noll.com/wiki/Running_Hadoop_On_Ubuntu_Linux_%28Single-Node_Cluster%29
Looks like datanode is not starting seems, (I am seeing only namenode, jobtracker) [EMAIL PROTECTED] hadoop]$ /usr/local/hadoop/bin/start-all.sh starting namenode, logging to /usr/local/hadoop/bin/../logs/hadoop-hadoop-namenode-gis14.out /bin/bash: /root/.bashrc: Permission denied localhost: ssh: localhost: Name or service not known /bin/bash: /root/.bashrc: Permission denied localhost: ssh: localhost: Name or service not known starting jobtracker, logging to /usr/local/hadoop/bin/../logs/hadoop-hadoop-jobtracker-gis14.out /bin/bash: /root/.bashrc: Permission denied localhost: ssh: localhost: Name or service not known Then when I try to copy Local file to HDFS, I am getting this error. [EMAIL PROTECTED] hadoop]$ /usr/local/hadoop/bin/hadoop dfs -ls Found 0 items [EMAIL PROTECTED] hadoop]$ /usr/local/hadoop/bin/hadoop dfs -copyFromLocal /tmp/guten gutenberg copyFromLocal: java.io.IOException: Failed to create file /user/hadoop/gutenberg/7ldvc10.txt on client xxx.xxx.xxx.xxx because this cluster has no datanodes. [EMAIL PROTECTED] hadoop]$ /usr/local/hadoop/bin/hadoop dfs -ls Found 1 items /user/hadoop/gutenberg <dir> 2008-01-02 15:51 [EMAIL PROTECTED] hadoop]$ /usr/local/hadoop/bin/hadoop dfs -ls gutenberg Found 0 items I couldn't find any log file corresponding to datanode. Could you please let me know what might the problem. Thanks, Senthil
