title: Installing PredictionIO from Source Code
---

INFO: Assuming you are following the directory structure in the followoing,
replace `/home/abc` with your own home directory wherever you see it.

## Building

Run the following to download and build PredictionIO from its source code.

```
$ git clone https://github.com/PredictionIO/PredictionIO.git
$ cd PredictionIO
$ git checkout master
$ ./make-distribution.sh
```

You should see something like the following when it finishes building
successfully.

```
...
PredictionIO-<%= data.versions.pio %>/sbt/sbt
PredictionIO-<%= data.versions.pio %>/conf/
PredictionIO-<%= data.versions.pio %>/conf/pio-env.sh
PredictionIO binary distribution created at PredictionIO-<%= data.versions.pio %>.tar.gz
```

Extract the binary distribution you have just built.

```
$ tar zxvf PredictionIO-<%= data.versions.pio %>.tar.gz
```


## Installing Dependencies

Let us install dependencies inside a subdirectory of the PredictionIO
installation. By following this convention, you can use PredictionIO's default
configuration as is.

```
$ mkdir PredictionIO-<%= data.versions.pio %>/vendors
```


### Spark Setup

<%= partial 'shared/install/spark' %>


### Storage Setup

#### Elasticsearch Setup

<%= partial 'shared/install/elasticsearch' %>


#### <a name="hbase"></a>HBase Setup

<%= partial 'shared/install/hbase' %>


In addition, you must set your environment variable `JAVA_HOME`. For example, in
`/home/abc/.bashrc` add the following line:

```
export JAVA_HOME=/usr/lib/jvm/java-8-oracle
```


<%= partial 'shared/install/dependent_services' %>

Now you have installed everything you need!
