Build from Source Code
Download BigDL Source
BigDL source code is available at GitHub
$ git clone https://github.com/intel-analytics/BigDL.git
git clone will download the development version of BigDL, if you want a release version, you can use command
git checkout to change the version. Available release versions is BigDL releases.
Setup Build Environment
The following instructions are aligned with master code.
Maven 3 is needed to build BigDL, you can download it from the maven website.
After installing Maven 3, please set the environment variable MAVEN_OPTS as follows:
$ export MAVEN_OPTS="-Xmx2g -XX:ReservedCodeCacheSize=512m"
When compiling with Java 7, you need to add the option “-XX:MaxPermSize=1G”.
Build with script (Recommended)
It is highly recommended that you build BigDL using the make-dist.sh script. And it will handle the MAVEN_OPTS variable.
Once downloaded, you can build BigDL with one of the following commands:
For Spark 2.0 and above (using Scala 2.11)
$ bash make-dist.sh -P spark_2.x
It is highly recommended to use Java 8 when running with Spark 2.x; otherwise you may observe very poor performance.
For Spark 1.5.x or 1.6.x (using Scala 2.10)
$ bash make-dist.sh
Specify a Scala version
make-dist.sh uses Scala 2.10 for Spark 1.5.x or 1.6.x, and Scala 2.11 for Spark 2.0.x or 2.1.x. To override the default behaviors, you can pass
-P scala_2.10 or
-P scala_2.11 to
make-dist.sh as appropriate.
After that, you can find a
dist folder, which contains all the needed files to run a BigDL program. The files in
- dist/bin/: The folder contains scripts used to set up proper environment variables and launch the BigDL program.
- dist/lib/bigdl-VERSION-jar-with-dependencies.jar: This jar package contains all dependencies except Spark classes.
- dist/lib/bigdl-VERSION-python-api.zip: This zip package contains all Python files of BigDL.
- dist/conf/spark-bigdl.conf: This file contains necessary property configurations.
Engine.createSparkConfwill populate these properties, so try to use that method in your code. Or you need to pass the file to Spark with the "--properties-file" option.
Build with Maven
To build BigDL directly using Maven, run the command below:
$ mvn clean package -DskipTests
After that, you can find that the three jar packages in
PATH_To_BigDL is the path to the directory of the BigDL.
Note that the instructions above will build BigDL with Spark 1.5.x or 1.6.x (using Scala 2.10) for Linux, and skip the build of native library code. Similarly, you may customize the default behaviors by passing the following parameters to maven:
-P spark_2.x: build for Spark 2.0 and above (using Scala 2.11). (Again, it is highly recommended to use Java 8 when running with Spark 2.0; otherwise you may observe very poor performance.)
-P full-build: full build
-P scala_2.11): build using Scala 2.10 (or Scala 2.11)
We set the scope of spark related library to
provided in pom.xml. The reason is that we don't want package spark related jars which will make bigdl a huge jar, and generally as bigdl is invoked by spark-submit, these dependencies will be provided by spark at run-time.
This will cause a problem in IDE. When you run applications, it will throw
NoClassDefFoundError because the library scope is
You can easily change the scopes by the
- In Intellij, go to View -> Tools Windows -> Maven Projects. Then in the Maven Projects panel, Profiles -> click "all-in-one".
