| Changing Storage Setup |
| =================== |
| |
| PredictionIO relies on a data store to store its metadata. At the moment, PredictionIO's storage layer supports [Elasticsearch](http://www.elasticsearch.org/). Make sure you have it running and functioning properly on your computer. |
| |
| 1. If you are using Elasticsearch at the localhost and its default settings, you may stop here. |
| |
| 2. Otherwise, change the following in `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 |
| ``` |
| <!-- |
| If you use MongoDB, add and modify the following to fit your setup. |
| |
| ``` |
| PIO_STORAGE_SOURCES_MONGODB_TYPE=mongodb |
| PIO_STORAGE_SOURCES_MONGODB_HOSTS=localhost |
| PIO_STORAGE_SOURCES_MONGODB_PORTS=27017 |
| ``` |
| |
| 3. The following points the storage repositories to their respective backend |
| data sources. By default, they point to Elasticsearch. |
| |
| ``` |
| PIO_STORAGE_REPOSITORIES_METADATA_SOURCE=ELASTICSEARCH |
| ``` |
| |
| If you use MongoDB, change them to something like this. |
| |
| ``` |
| PIO_STORAGE_REPOSITORIES_METADATA_SOURCE=MONGODB |
| ``` |
| --> |
| |
| Save ``conf/pio-env.sh`` and you are done! |
