Information and setting for ES mapping generation are configured in es_mapper.yaml. Elasticsearch mappings/settings can then be generated programmatically with this command:
python es-mapping-gen.py
To create ES index for file_centric with the latest version of mapping/settings, simply do this:
curl -XPUT -H 'Content-Type: application/json' "localhost:9200/file_centric" -d @es-model-latest/file_centric.mapping.json
