How can I set  HADOOP _HOME? in which file I can find this variable? I
should set this variable with the path in that I downloaded hadoop?

Hi Babak,

    You can use export command from the shell to set HADOOO_HOME, but
it will be lost once you close the terminal. To set ir permanently add
the following line to the ".bashrc" file present in your
/home/your_username/ directory -

export HADOOP_HOME=/path_of_your_hadoop_folder

You can use this to set any variable permanently. Restart your system
in order to apply the changes.

DO this:-

nano ~/.bashrc
add following lines:-
export HADOOP_HOME= (path to your hadoop bin directory)

#done

Hi

If you are looking to set HADOOP_HOME just for hive, you can do that at hive_env.sh .

For your question, yes it is location (hadoop parent dir) where you have extracted your tall ball.

Babak,
For what it's worth, HADOOP_HOME has been deprecated starting Hadoop 0.23
