Hello Mac User! This Tutorial Shows You Step-by-Step How-to Install Hadoop on Mac Sierra 10.12 OS X. Especially relevant: this is a Vanilla Hadoop Install on Mac. It is an introduction of Hadoop installation under pseudo-distributed model. The difference among single node, pseudo-distributed and distributed is introduced here: link. Install Homebrew and Cask Homebrew is a free and open-source software package management system that simplifies the installation of software on Apple’s macOS operating system.

This allows for creating an installer for Hadoop for Mac OS X that attempts to integrate Hadoop in a typical manner with the OS:

  • Most files are put in /Library/Cloudera.
  • launchd will be used for stopping and starting the various daemons.
  • Paths are added to PATH by way of /etc/paths.d.


  • Daemons don't correctly start up for Hadoop and I haven't done anything yet for ZooKeeper.
  • I haven't put HBase, Hive, Flume or Hue in here yet.
  • Permissions are not quite right yet for various files. This is pretty frustrating.
  • It would be nice to automate setting JAVA_HOME for those things that need it. (This is just a matter of setting JAVA_HOME to the output of /usr/libexec/java_home.)
  • I haven't done anything to deal with updating to newer versions yet.


  • To build the installer, you download the various .tar.gz files from Cloudera, unpack them and put them in the right places under dist such as dist/Hadoop/Library/Cloudera/hadoop-0.20.2+737.
  • There are symlinks without version numbers (and capitalized) that all go into /Library/Cloudera on the target system. If the version being installed changes, then the symlink must also be updated.
  • I will have another script added at some point that handles setting up the permissions correctly once I figure out what all is needed there.
  • I run the CDH3.pmdoc/*.xml files through xmllint to format them nicer for diffs with the prettyxml.sh script.
Latest Hadoop setting on Mac OS X can be achieved by various ways like Homebrew. If you don’t prefer Homebrew, this guide aims to setting up the pseudo-distributed mode in single node cluster.

1. Required software

1) Java

Run the following command in a terminal:
If Java is already installed, you can see a similar result like:
If not, the terminal will prompt you for installation or you can download Java JDK here.

2) SSH

First enable Remote Login in System Preference -> Sharing.
Now check that you can ssh to the localhost without a passphrase:
If you cannot ssh to localhost without a passphrase, execute the following commands:

2. Get a Hadoop distribution

3. Prepare to start the Hadoop cluster

1) Unpack the downloaded Hadoop distribution.

2) Run the following command to figure out where is your Java home directory:
3) In the distribution, edit the file etc/hadoop/hadoop-env.sh to define some parameters as follows:
This will display the usage documentation for the hadoop script.
Now you are ready to start your Hadoop cluster in one of the three supported modes:
  • Standalone mode
  • Pseudo-distributed mode
  • fully-distributed mode
We will go through pseudo-distributed mode and run a MapReduce job on YARN here. In this mode, Hadoop runs on a single node and each Hadoop daemon runs in a separate Java process.

4. Configuration

Edit following config files in your Hadoop directory
1) etc/hadoop/core-site.xml:
2) etc/hadoop/hdfs-site.xml:
4) etc/hadoop/yarn-site.xml:


5. Execution

Mac Os X For Pc

Format the filesystem:
Start NameNode daemon and DataNode daemon:
Now you can browse the web interface for the NameNode at - http://localhost:50070/
Make the HDFS directories required to execute MapReduce jobs:

Start ResourceManager daemon and NodeManager daemon:
Browse the web interface for the ResourceManager at - http://localhost:8088/
2) Test examples code that came with the hadoop version

Copy the input files into the distributed filesystem:
This example counts the words starting with 'dfs' in the input.
Copy the output files from the distributed filesystem to the local filesystem and examine them:
or View the output files on the distributed filesystem:
3) Stop YARN and HDFS
