How to import JSON file to ElasticSearch 6.x?
Use the --data-binary flag in curl to bulk import from a JSON file.
curl -H 'Content-Type: application/x-ndjson' -XPOST 'localhost:9200/{index}/{type}/_bulk?pretty' --data-binary @es.jsonData can be posted to one of the endpoints - /_bulk, /{index}/_bulk or {index}/{type}/_bulk. When {index} or {index}/{type} is provided, they will be used by default on bulk items that don’t provide them explicitly.
Content-Type: application/x-ndjson stands for Newline delimited JSON.
Before importing the JSON file, you might want to define mappings yourself or let Elasticsearch generate mappings dynamically during import. If you don't want Elasticsearch to generate mappings dynamically during import, refer to this doc to define mappings yourself.

You can use elasticsearch_loader for loading json files into elasticsearch (2.X, 5.X, 6.X).
You can download it with pip:
pip install elasticsearch-loaderAnd then you will be able to load json files into elasticsearch by issuing:
elasticsearch_loader --index incidents --type incident json file1.json file2.jsonDisclaimer: I'm the author of elasticsearch_loader
