I am trying to check my installation of hadoop. I did create the environment variables and when I call printenv , I do see my HADOOP_HOME and PATH variables printed and correct (home/hadoop and HADOOP_HOME/bin respectively). If I go to home/hadoop in the terminal and call ls , I see the hadoop file there. If I try to run it by calling hadoop , it still tells me command not found. First day on Linux, so there may be a stupid answer to this problem.

If you are in the same directory, where your hadoop file is, run that command with an relative path, like: ./hadoop

/home/hadoop is a home directory created by linux similar to Document and settings in windows.
Open your terminal and type:
ls -l /home/hadoop Post your result for this command: ls -l /home/hadoop
SETTING GLOBAL PATH:
Go to /home/hadoop and open .bashrc in text editor. Add these lines at the end:
export HADOOP_HOME=/path/to/your/hadoop/installation/folder export PATH=$PATH:$HADOOP_HOME/bin Save and exit. Now type, this in your teminal:
echo $PATH echo $HADOOP_HOME If these commands shows correct directories, try hadoop command. It should work.

I am just trying to set up hadoop on my ubuntu machine and I was following this link tutorial. After modifying the configuration files mentioned in the tutorial, when I run hadoop version it still gives me hadoop: command not found . The results for the commands posted in this answer are in the following comment.
