Building Alluxio Master Branch
- Unit Tests
- Compute Framework Support
- Distro Support
- System Settings
This guide describes how to compile Alluxio from the beginning.
Checkout the Alluxio master branch from Github and package:
git clone git://github.com/alluxio/alluxio.git cd alluxio mvn install -DskipTests
If you are seeing
java.lang.OutOfMemoryError: Java heap space, please execute:
export MAVEN_OPTS="-Xmx2g -XX:MaxPermSize=512M -XX:ReservedCodeCacheSize=512m"
If you want to build a particular version of Alluxio, for example 1.5.0, please do
git checkout v1.5.0 after
The Maven build system fetches its dependencies, compiles source code, runs unit tests, and packages the system. If this is the first time you are building the project, it can take a while to download all the dependencies. Subsequent builds, however, will be much faster.
Once Alluxio is built, you can start it with:
./bin/alluxio format ./bin/alluxio-start.sh local
To verify that Alluxio is running, you can visit http://localhost:19999 or check the log in the
alluxio/logs directory. You can also run a simple program:
You should be able to see results similar to the following:

You can also stop the system by using:
To run all unit tests:
To run all the unit tests with under storage other than local filesystem:
mvn test [ -Dhadoop.version=x.x.x ] [ -P<under-storage-profile> ]

To have the logs output to STDOUT, append the following to the
Compute Framework Support
To build Alluxio against different compute frameworks, you can run Maven build with different compute profiles. The generated Alluxio client is located at
You can run the following command to compile Alluxio with Hadoop.
mvn install -P<HADOOP_PROFILE> -DskipTests
Available Hadoop profiles include
different distributions of Hadoop. You can further set a specific Hadoop release version to
compile by checking out this section.
You can run the following command to compile Alluxio with Spark
mvn install -Pspark -DskipTests
You can run the following command to compile Alluxio with Flink
mvn install -Pflink -DskipTests
You can run the following command to compile Alluxio with Presto
mvn install -Ppresto -DskipTests
To build Alluxio against one of the different distros of hadoop, you only need to change the
hadoop.version. You can run the following command:
mvn install -P<HADOOP_PROFILE> -Dhadoop.version=<HADOOP_VERSION> -DskipTests
<HADOOP_VERSION> can be set for different distributions.
All main builds are from Apache so all Apache releases can be used directly
-Dhadoop.version=2.2.0 -Dhadoop.version=2.3.0 -Dhadoop.version=2.4.0
To build against Cloudera’s releases, just use a version like
To build against a MapR release
-Dhadoop.version=2.7.0-mapr-1607 -Dhadoop.version=2.7.0-mapr-1602 -Dhadoop.version=2.7.0-mapr-1506 -Dhadoop.version=2.3.0-mapr-4.0.0-FCS
To build against a Pivotal release, just use a version like
To build against a Hortonworks release, just use a version like
-Dhadoop.version=184.108.40.206.0.5.0-67 -Dhadoop.version=220.127.116.11.1.0.0-92 -Dhadoop.version=18.104.22.168.1.3.0-563
Sometimes you will need to play with a few system settings in order to have the unit tests pass locally. A common setting that may need to be set is ulimit.
In order to increase the number of files and processes allowed, run the following
sudo launchctl limit maxfiles 16384 16384 sudo launchctl limit maxproc 2048 2048
It is also recommended to exclude your local clone of Alluxio from Spotlight indexing. Otherwise, your Mac may hang constantly trying to re-index the file system during the unit tests. To do this, go to
System Preferences > Spotlight > Privacy, click the
+ button, browse to the directory containing your local clone of Alluxio, and click
Choose to add it to the exclusions list.
