  1. 3. Extracting Hadoop

    Then Extract into /tmp
    Possibly Double-Click/Right-Click and Open with Archive Manager:

    Or from Shell:

    tar xvzf *hadoop*tar.gz -C /tmp
  2. 4. Installing Hadoop

    And to Install Apache Hadoop
    Get SuperUser Privileges (This simply to make shorter the command’s series):

    sudo su

    If Got “User is Not in Sudoers file” then see: How to Enable sudo
    Then Switch the contents with:

    mv /tmp/hadoop* /usr/local/

    Moreover, make an hadoop symlink directory:

    ln -s /usr/local/hadoop* /usr/local/hadoop
  3. 5. Setting Up Directories

    Make Hadoop Needed Directories:

    First, Make the Logs Dir:

    mkdir /usr/local/hadoop/logs

    Giving Writing Permissions:

    chmod 777 /usr/local/hadoop/logs

    Next Make the Cache Dir:

    mkdir /usr/local/hadoop/cache

    Same Writing Permissions as for Logs:

    chmod 777 /usr/local/hadoop/cache

    And then also the Temporary Dir:

    mkdir /usr/local/hadoop/tmp

    And Set the root as Owner:

    sudo chown -R root:root /usr/local/hadoop*
  4. 6. Installing Java JDK

    How to Install Required Java JDK 8+ on Fedora

    Install Oracle JDK 8+ for Fedora
  5. 7. Setting Up Variable

    Set JAVA_HOME in Hadoop Env File
    First, Make the Conf directory:

    mkdir /usr/local/hadoop/conf

    And then Make an Env file:

    nano /usr/local/hadoop/conf/hadoop-env.sh

    So now Append:

    export JAVA_HOME=/usr/lib/jvm/[oracleJdkVersion]

    Change [oracleJdkVersion] with the current Version:
    Ctrl+x to Save & Exit from nano Editor :)
