PredictionIO is an open source Machine Learning Server built on top of state-of-the-art open source stack for developers and data scientists create predictive engines for any machine learning task. PredictionIO cookbook aims to provide two variants of installation standalone and all-in-one (AIO).
The standalone variant installs and configures a system to run PIO EventServer/PredictionServer or a PIO driver machines. This installs the PIO stack sources (Hadoop/HBase/Spark), builds PIO and writes its configuration files.
The second variant is AIO installs and sets the system up with all the required services on a single machine. Apache dependencies such as Hadoop/HBase/Spark are configured in Pseudo Distributed mode. It's strongly suggested to the end-user to use this variant to evaluate PredictionIO.
- PredictionIO - 0.12.1
- Universal Recommender - 0.7.3

Actually any systemd/upstart based system should work smooth, though there are cookbook metadata restrictions for the given platforms. Feel free to change this, please open a PR and contribute.
This cookbooks contains quite a long list of attributes, we won't try to cover all of them here rather than just try to introduce the most important ones to you. For the complete list see attributes/.
| Attribute | Description | Default value |
|---|---|---|
| pio.user | User used for operating PredictionIO. | 'aml' |
| pio.home | PIO user's home directory. Specify to change the default (/opt/data/aml-home which is symlinked to /home/aml). |
'' |
| pio.localdir | Directory containing all the installed applications and services. | '/usr/local' |
| pio.datadir | Directory used as the top data store for all the installed services. | '/opt/data' |
| pio.pio.install_method | Specifies PredictionIO installation method (either binary source) |
'source' |
| pio.ur.git* | Attributes setting the Universal Recommender Git source location and version. | |
| pio.conf.event_server | Specifies the PredictionIO Event Server port. | 7070 |
| pio.conf.prediction_server | Specifies the PredictionIO Prediction Server port. | 8000 |
| pio.hdfs_structure | Specifies initial HDFS layout to bootstrap. | see attributes |
For the standalone installation, include pio recipe in your node's run_list.
For the AIO installation, include pio::aio recipe in your node's run_list.
