    I literally installed it 3 times in my college lab system but the instructions were so unclear, I couldn't install it properly at all. I watched this video and installed it on my Virtual Box Ubuntu and I FINALLY FINALLY FINALLY GOT IT 😭😭😭😭😭🎉🎉🎉 Thank you so so so much for this video!!!

    guys, there is a slight change while editing .bashrc file @9:22 of the video where the last line is
    export HADOOP_OPTS"-Djava.library.path=$HADOOP_HOME/lib/nativ"
    please change it to
    export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib/native"
    later when you type
    source .bashrc
    it won't throw any errors
    thank you.

    Thank you for making this video, it really helped me! I'm in a Big Data training right now, and I've been trying to install Hadoop properly for weeks at this point. The only error I got this time was "port 22: Connection Refused" when using the ssh localhost command. I followed a suggestion from Stack Overflow and did "sudo service ssh restart". Then ssh localhost worked fine for me, and I was able to continue with the rest of your instructions. Thank you!!

    Now my question is will system automatically create this directories at the back end ?
    Or we have to manually create and give the mentioned path that are given in the document?

    Hello sir
    In your video at 10:36 you talk about that command which is sudo adduser Hadoop sudo before which we type like in your case it is (su - aman)
    For me it is
    su - dhruv
    After that it asks for password
    And it comes as
    su : Authentication failure
    What should I do now?
