Set environmental variables

You can discover Java JDK for JAVA_HOME with which javac and do ls -l to follow the symlinks

JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.101-3.b13.el7_2.x86_64
PIO_HOME=/opt/predictionio
PATH=$PATH:$PIO_HOME/bin

Download to /opt

cd /opt
git clone https://github.com/apache/incubator-predictionio.git predictionio
cd predictionio

NOTE: During the transition to the Apache ASF predictionion the URLs in the pio documentation might be unreliable, you can use action-ml fork in the meantime:

git clone https://github.com/actionml/PredictionIO.git predictionio

Make sure you are on the master branch or use the tag for the desired release version.

Download vendors

mkdir -p vendors
cd vendors
curl https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-1.4.4.tar.gz | tar xvz && mv elasticsearch-1.4.4 elasticsearch
curl http://d3kbcqa49mib13.cloudfront.net/spark-1.5.1-bin-hadoop2.6.tgz | tar xvz && mv spark-1.5.1 spark
curl http://archive.apache.org/dist/hbase/1.1.2/hbase-1.1.2-bin.tar.gz | tar xvz && mv hbase-1.1.2 hbase

Modify the configuration

Go to cd $PIO_HOME && vim conf/pio_env.sh and add

#!/usr/bin/env bash

# SPARK_HOME: Apache Spark is a hard dependency and must be configured.
SPARK_HOME=$PIO_HOME/vendors/spark

# Filesystem paths where PredictionIO uses as block storage.
PIO_FS_BASEDIR=$HOME/.pio_store
PIO_FS_ENGINESDIR=$PIO_FS_BASEDIR/engines
PIO_FS_TMPDIR=$PIO_FS_BASEDIR/tmp

# PredictionIO Storage Configuration

Create systemd services for vendors and pio event server and deploy

Refer to infrastructure repo to retrieve the templates name.service to place them in /usr/lib/systemd/system/ for:

• elasticsearch.service
• hbase.service
• pioeventserver.service
• pio.service

Start the services

Use systemctl start service, and check status with journalctl -xe.

Check status

# Event server
curl -XGET PIO_ADDRESS:7070

# PIO Engine server
curl -XGET PIO_ADDRESS:8000

where will I find the infrastructure repo?
please help me with that
