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.
Your current working directory is probably not part of your path. That is default on linux systems.
If you are in the same directory, where your
hadoop file is, run that command with an relative path, like:
/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:
/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.
Post your result for these command: echo $PATH and echo $HADOOP_HOME
which hadoop in your terminal. If you see a path as an output, hadoop is set in PATH of your system. If you get something similar to this,
usr/bin/which: no hadoop in (/usr/local/hadoop.... you might not have setup everything properly. Modify the
export HADOOP_HOME = /path/to/hadoop/folder and add it to PATH using
