Editing the ~/.bashrc file for hadoop installation

  • 772

I have been trying to install hadoop-2.6.0 in my Ubuntu 16.04 machine. I have been logged into the hduser from another user krishna by:

sudo su hduser

and the hduser then gets into its use.

After that i entered the command:

vi ~/.bashrc

This opens the file in read-only mode but I am not getting the write access so that I can append a set of statements into it.

command-line

    To troubleshoot you should first run the command:

    ls -l /home/hduser/.bashrc

    It will display:

    -rw-r--r-- 1 hduser   186 Jun 27 15:27 /home/hduser/.bashrc

    The first column (-rw-r--r--) lists permissions, the third one (hduset) the file owner. If the owner is not hduser but root, you'd need to run:

    sudo chown hduser /home/hduser/.bashrc

    If there was a hduser listed as the owner, but permissions would not contain w, you'd need to run:

    sudo chmod u+w /home/hduser/.bashrc
