Prerequisites

It is very important to meet the minimum version of the following technologies that power Apache PredictionIO®.

  • Apache Hadoop 2.6.5 (optional, required only if YARN and HDFS are needed)
  • Apache Spark 2.0.2 for Hadoop 2.6
  • Java SE Development Kit 8

and one of the following sets:

  • PostgreSQL 9.1

or

  • MySQL 5.1

or

  • Apache HBase 0.98.5
  • Elasticsearch 1.7.6

Note that support for Scala 2.10 and Spark 1.6 were removed as of PredictionIO 0.14.0. Note that support for Elasticsearch 1 is deprecated as of PredictionIO 0.14.0.

If you are running on a single machine, we recommend a minimum of 2GB memory.

If you are using Linux, Apache Spark local mode, which is the default operation mode without further configuration, may not work. In that case, configure your Apache Spark to run in standalone cluster mode.

Installation

You may also use Docker to install Apache PredictionIO®

0.8.2 contains schema changes from the previous versions, if you have installed the previous versions, you may need to clear both HBase and Elasticsearch. See more here.
