I have been referring to this link for hadoop-1.1.1 installation.

All my files and permissions have been set according to this link. But I am getting this error.Please help.

  • Have you formatted the namenode before doing "bin/start-all.sh". Looks like your namenode is not formatted properly. Commented Feb 28, 2013 at 15:07
  • Furthermore please check the permissions to /usr/local/hadoop/log/. Can you access this directory as hduser? Commented Feb 28, 2013 at 18:18

As the error suggests you're having a permission problem. You need to give hduser proper permissions. Try:

sudo chown -R hduser /usr/local/hadoop/

Run this command to change the permission of the hadoop directory

Below are 2 very helpful suggestions:

  1. It is good to check whether HADOOP_HOME and JAVA_HOME is set in .bashrc file. Sometimes, not setting up these environment variables may also cause error while starting the hadoop cluster.

  2. It is also useful to debug the error by going through the log files generated in /usr/local/hadoop/logs directory.
