Step 3: Install Hadoop. Download hadoop 2.7.3 binary zip file from this link (200MB). Extract the contents of the zip to a folder of your choice. Step 4: Configure Hadoop. First we need to configure the location of our Java installation in etc/hadoop/hadoop-env.sh. To find the location of Java installation, run the following command on the. Setting up Hadoop 2.6 on Mac OS X Yosemite. After comparing different guides on the internet, I ended up my own version base on the Hadoop official guide with manual download. If you prefer Homebrew, this one would be your best choice. Actually there is no difference in the configuration of these two methods except the file directories. Step 1 - Download Hadoop binary package Select download mirror link. Go to download page of the official website: Apache Download Mirrors - Hadoop 3.3.0. And then choose one of the mirror link. The page lists the mirrors closest to you based on your location. Hadoop is released as source code tarballs with corresponding binary tarballs for convenience. The downloads are distributed via mirror sites and should be checked for tampering using GPG or SHA-512.

Need to install Hadoop for a class or a project? It can be hard. It took me 1 hour to install and that was after clear instructions provided by Professor.

So I did what a good Software Engineer does and automated it.

Comic credit: Automation by xkcd.

In this post, I will cover two ways to install Hadoop:

1. Automatic install in 5 minutes
2. Manual install in 15ish minutes

Download Hadoop For Mac Os X

Unless you are a Software Engineer who wants to install it manually, I’d recommend going with Vagrant as it’s faster and you don’t have to fiddle with you OS.

What Is Hadoop

Vagrant also has an added benefit of keeping your local OS clean and not having to install and troubleshoot different versions of jdk and other packages.

Installing Hadoop in 5 Minutes with Vagrant

1. Make sure you have latest versions of VirtualBox and Vagrant installed.
2. Download or clone Vagrant Hadoop repository.
3. Navigate to the directory where you downloaded the repo using command line (want to learn command line? I’ve got you covered: 7 Essential Linux Commands You Need To Know)
4. Run vagrant up
5. Done

That’s it. Once installation is done, run vagrant ssh to access your vagrant machine and use Hadoop.

Installing Hadoop Manually on macOS and Linux

Warning: I’ve only tested these instructions on Linux (Ubuntu to be specific). On macOS, you may need to use different folders or install additional software.

Here are the instructions:

1. Make sure that apt-get knows about latest repos using sudo apt-get update
2. Install Java
   sudo apt-get install openjdk-11-jdk
3. Download Hadoop
   wget http://mirrors.koehn.com/apache/hadoop/common/hadoop-3.2.0/hadoop-3.2.0.tar.gz
4. Copy Hadoop files to /usr/local/bin (this is a personal preference, you can copy to any folder, just make sure you change the commands going forward)
   sudo tar -xvzf hadoop-3.2.0.tar.gz -C /usr/local/bin/
5. Rename the hadoop folder. Again, this is a personal preference, you can leave it the way you want but you’ll need to change the paths going forward.
   sudo mv /usr/local/bin/hadoop-3.2.0 /usr/local/bin/hadoop/
6. Update path variables:
   

   echo'export JAVA_HOME=/usr'>> /home/vagrant/.bashrc

   echo'export HADOOP_LOG_DIR=/hadoop_logs'>> /home/vagrant/.bashrc

   echo'export PATH=$PATH:/usr/local/bin/hadoop/bin:/usr/local/bin/hadoop/sbin'>> /home/vagrant/.bashrc

   source~/.bashrc

7. Update Hadoop environment variables:
   

   echo'export JAVA_HOME=/usr'| sudo tee --append /usr/local/bin/hadoop/etc/hadoop/hadoop-env.sh

   echo'export HADOOP_LOG_DIR=/hadoop_logs'| sudo tee --append /usr/local/bin/hadoop/etc/hadoop/hadoop-env.sh

   echo'export HDFS_NAMENODE_USER='vagrant''| sudo tee --append /usr/local/bin/hadoop/etc/hadoop/hadoop-env.sh

   echo'export HDFS_DATANODE_USER='vagrant''| sudo tee --append /usr/local/bin/hadoop/etc/hadoop/hadoop-env.sh

   echo'export HDFS_SECONDARYNAMENODE_USER='vagrant''| sudo tee --append /usr/local/bin/hadoop/etc/hadoop/hadoop-env.sh

   echo'export YARN_RESOURCEMANAGER_USER='vagrant''| sudo tee --append /usr/local/bin/hadoop/etc/hadoop/hadoop-env.sh

   echo'export YARN_NODEMANAGER_USER='vagrant''| sudo tee --append /usr/local/bin/hadoop/etc/hadoop/hadoop-env.sh

8. Generate a SSH key and add it to authorized_keys (thanks to Stack Overflow user sapy: Hadoop “Permission denied” warning)
   

   ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa

   cat /home/vagrant/.ssh/id_rsa.pub >>~/.ssh/authorized_keys

9. You’ll need to edit the /usr/local/bin/hadoop/etc/hadoop/core-site.xml file to add fs.defaultFS setting. Here’s my configuration file:

   <?xml version='1.0' encoding='UTF-8'?>

   <?xml-stylesheet type='text/xsl' href='configuration.xsl'?>

   <configuration>

   <property>

   <name>fs.defaultFS</name>

   <value>hdfs://localhost:9000</value>

   </property>

   </configuration>

10. Next, edit the /usr/local/bin/hadoop/etc/hadoop/hdfs-site.xml file to add 3 properties. As SachinJ noted on Stack Overlow, hdfs will reset every time you reboot your OS without the first two of these. (Hadoop namenode needs to be formatted after every computer start)

    <?xml version='1.0' encoding='UTF-8'?>

    <?xml-stylesheet type='text/xsl' href='configuration.xsl'?>

    </property>

    <property>

    <name>dfs.replication</name>

    <value>1</value>

    </property>

    </configuration>

11. Initialize the hdfs
    /usr/local/bin/hadoop/bin/hdfs namenode -format
12. Run dfs using /usr/local/bin/hadoop/sbin/start-dfs.sh
13. Test everything is running fine by creating a directory in hdfs using hdfs dfs -mkdir /test

That’s it. If you got Hadoop working, do share the post to help others.
