| [Elasticsearch](https://www.elastic.co/) can be used as a storage backend for |
| the meta data repository. |
| |
| INFO: Starting from 0.11.0, if you build PredictionIO against Elasticsearch 5+, |
| you may also use it as a backend for the event data repository. |
| |
| ``` |
| $ wget https://artifacts.elastic.co/downloads/elasticsearch/<%= data.versions.elasticsearch_download_filename %>.tar.gz |
| $ tar zxvfC <%= data.versions.elasticsearch_download_filename %>.tar.gz PredictionIO-<%= data.versions.pio %>/vendors |
| ``` |
| |
| INFO: If you decide to install Elasticsearch to another location, you must edit |
| `PredictionIO-<%= data.versions.pio %>/conf/pio-env.sh` and change the |
| `PIO_STORAGE_SOURCES_ELASTICSEARCH_HOME` variable to point to your own |
| Elasticsearch installation. |
| |
| INFO: If you are using a shared network, change the `network.host` line in |
| `PredictionIO-<%= data.versions.pio %>/vendors/<%= |
| data.versions.elasticsearch_download_filename %>/config/elasticsearch.yml` to |
| `network.host: 127.0.0.1` because by default, Elasticsearch looks for other |
| machines on the network upon setup and you may run into weird errors if there |
| are other machines that is also running Elasticsearch. |
| |
| If you are not using the default setting at `localhost`, you may change the |
| following in `PredictionIO-<%= data.versions.pio %>/conf/pio-env.sh` to fit your |
| setup. |
| |
| ``` |
| PIO_STORAGE_SOURCES_ELASTICSEARCH_TYPE=elasticsearch |
| PIO_STORAGE_SOURCES_ELASTICSEARCH_HOSTS=localhost |
| PIO_STORAGE_SOURCES_ELASTICSEARCH_PORTS=9300 |
| ``` |
