PredictionIO is a source only release so you will need to build it.

  • Build PredictionIO

    Dowload the latest PredictionIO source Apache's Github here.

    $ tar zxvf apache-predictionio-0.12.1.tar.gz
$ cd apache-predictionio-0.11.0-incubating
$ ./make-distribution.sh

    This will create a tarball inside apache-predictionio-0.12.1 extract it with

    tar zxvf PredictionIO-0.12.1.tar.gz

    We suggest you move the resulting PredictionIO-0.11.0-incubating directory

    mv PredictionIO-0.11.0-incubating /opt/pio
sudo ln -s /opt/PredictionIO-0.12.1 /usr/local/pio

    PredictionIO will not run yet so read on.

  • Setup Path for PIO commands. Add PIO to the path by editing your ~/.profile on the master. Here is an example of the important values I have in the file.

    # Java
export JAVA_OPTS="-Xmx4g"
# You may need to experiment with this setting if you get 
# "out of memory error"" for the driver, executor memory and 
# Spark settings can be set in the
# sparkConf section of engine.json

# Spark
# this tells PIO which host to use for Spark
export MASTER=spark://some-master:7077
export SPARK_HOME=/usr/local/spark

# pio
export PATH=$PATH:/usr/local/pio/bin:/usr/local/pio

    Source these with

    . ~/.profile

    to get changes applied.
