The First Cry of Atom Today is the first day of the rest of my life.

Build Hadoop on MacOSX

I am not a veteran Java developer. I don’t understand the detail of Java development environment such as build tool or some type of libraries. Today, I realised that I need to develop or understand architecture of Hadoop. Hadoop seems to use some kind of Java development tools. Maven, ProtocolBuffer, CMake and so on. So in this article I want to record my environment for building hadoop projects on MacOSX.


You also can see this list on BUILDING.txt. On MacOSX, you don’t need to install JDK and openssl. Within this list, all you need to install are CMake and ProtocolBuffer.


Download from here. After unziping it, you can walk ordinal steps.

$ ./configure
$ make
$ make install


You can install CMake with Homebrew. It is the easiest way.

$ brew install cmake

All dependencies are installed on your machine now. Let’s checkout hadoop source code.

Hadoop Project

$ svn checkout

Notice: I tried hadoop GitHub repository, but it was very slow to download it. I recommend you to checkout from svn repository.

And build it.

$ mvn package -DskipTests -Pdist -Dtar

Because of some broken tests, you have to write skipTests option. With this command you can command line tools and jar files in hadoop-dist/target/hadoop-X.X.X-SNAPSHOT

$ bin/hadoop version
Subversion -r 1511192
Compiled by hadoopworld on 2013-08-07T07:01Z
From source with checksum c8f4bd45ac25c31b815f311b32ef17
This command was run using ~/work/trunk/hadoop-dist/target/hadoop-X.X.X-SNAPSHOT

All configuration files are under hadoop-dist directory. You can rewrite xml files to change Pseudo distributed mode from stand alone mode. After finishing all tasks, I found nothing was hard. I want study the detail of architecture and codebase of hadoop and start writing some patches for hadoop project. Thank you.
