hadoop command not found

Question

I hadoop installed in a linux machine. I have started the hadoop via the command /usr/local/hadoop/bin/start-all.sh and this is the prompt I am getting:

namenode running as process 7876. Stop it first.
localhost: datanode running as process 8083. Stop it first.
localhost: secondarynamenode running as process 8304. Stop it first.
jobtracker running as process 8398. Stop it first.
localhost: tasktracker running as process 8612. Stop it first

But when i am trying to push the data into hdfs using the command given below:

jeet@jeet-Vostro-2520:~$ hadoop fs -put gettysburg.txt /user/jeet/getty/gettysburg.txt
hadoop: command not found

I am new to Hadoop. Can someone help me to resolve the issue?

Answer 1

The reason you are getting hadoop as unknown command because you have not exported hadoop path in the environment variable. In order to solve it, you need to edit your .bashrc file Here, are the steps that you have to follow:

• open ~/.bashrc file (like gedit ~/.bashrc)
• Add the following lines in the same file and save it:

export PATH=$PATH:/usr/local/hadoop/bin/

Now you can run the hadoop commands from any directory.

Hi@Vashist,

Check your .bashrc file and set the HADOOP_HOME and PATH properly.

export HADOOP_HOME=(put the path where you have your Hadoop folder)

export PATH=HADOOP_HOME/bin:$PATH

If you still getting the same error, please share your .bashrc file.

Thank You
