This is what am getting when am trying to run following command . Kindly suggest what to do , i am new to ubuntu ,my hadoop is downloaded in /home/Downloads . Tried moving the already zipped file but i get an error no such file exits .

vivek@vivek-HP-15-Notebook-PC:/usr/local$ sudo tar xzf hadoop-2.7.1.tar.gz
[sudo] password for vivek: tar (child): hadoop-2.7.1.tar.gz:
Cannot open: No such file or directory tar (child):

Try running the command from the Downloads folder instead of /usr/local/ (or successfully move the file to /usr/local/ first if that is where it needs to be).


cd ~/Downloads

sudo tar xzf hadoop-2.7.1.tar.gz

$HOME/.bashrc file and edit it for a new user hduser ?

To move the file to /usr/local/ do..


sudo cp ~/Downloads/hadoop-2.7.1.tar.gz /usr/local/

then run the extract command.


sudo tar xzf /usr/local/hadoop-2.7.1.tar.gz

Check the files present in the folder with...


ls -l /usr/local/
