Put mapping in ElasticSearch by JAVA API

Question

I want to put mapping for a field by JAVA API but failed. Following is detailed information:

My data structure is :

{
  "mje-test-execution-id": "464b66ea6c914ddda217659c84a3cb9d",
  "jvm-free-memory": 315245608,
  "jvm-total-memory": 361758720,
  "system-free-memory": 0,
  "jvm-max-memory": 7600078848,
  "system-total-memory": 34199306240,
  "memory-time-stamp": "2020-03-12T05:12:16.835Z",
  "mje-host-name": "CN-00015345",
  "mje-test-suite-name": "SCF Test no mje version",
  "mje-version": "1.8.7771-SNAPSHOT",
  "mje-test-artifact-id": "msran-regression-tests",
  "mje-test-version": "1.8.7771-SNAPSHOT",
  "stp-id": "vran-stp",
  "mje-test-location": {
    "lat": 58.41,
    "lon": 15.62
  }
}

What I want to do is : put "mje-test-location" type to be "geo_point"

My code snippet :

public void postMapping(String indexName, String field, String type) throws IOException {
        GetIndexRequest request = new GetIndexRequest(indexName);

        boolean exists = client.indices().exists(request, RequestOptions.DEFAULT);
        if (!exists) {
            LOGGER.info("index {} does not exist. Now to post mapping.", indexName);
            PutMappingRequest putMappingRequest = new PutMappingRequest(indexName);
            XContentBuilder builder = XContentFactory.jsonBuilder();
            builder.startObject();
            {

                builder.startObject("properties");
                {
                    builder.startObject(field);
                    {
                        builder.field("type", type);
                    }
                    builder.endObject();
                }
                builder.endObject();
            }
            builder.endObject();
            putMappingRequest.source(builder);
            //

            AcknowledgedResponse putMappingResponse = client.indices().putMapping(putMappingRequest,
                    RequestOptions.DEFAULT);

            boolean acknowledged = putMappingResponse.isAcknowledged();
            if (acknowledged) {
                LOGGER.info("Succeed to put mapping: field:{}, type: {}", field, type);
            }
        }

        LOGGER.info("Fail to put mapping due to index {} already exist, ", indexName);
    }

Error info:

15:59:54.397 [main] DEBUG org.elasticsearch.client.RestClient - request [PUT http://seliiuapp00269.lmera.ericsson.se:9208/mje-scf-v2-20200313-post/_mapping?master_timeout=30s&timeout=30s] returned [HTTP/1.1 400 Bad Request]

If I understand, the method postMapping() is called for each field of your document ? — fmdaboville

@Littlesun, why you are calling this for each field, this would cause a lot of n/w calls, instead of that you should create a mapping in one go which includes all the fields — Amit

Yep, you should write a method postMapping(indexName), who handle all fields, with a json file for example or another method in : elastic.co/guide/en/elasticsearch/client/java-rest/master/… — fmdaboville

Maybe you imported the wrong type. What is the full name of your class "PutMappingRequest": org.elasticsearch.action.admin.indices.mapping.put.PutMappingRequest or org.elasticsearch.client.indices.PutMappingRequest? You should use the second one. — Mincong Huang

You need to specify the document type like this:

putMappingRequest.type("_doc");

And also need to specify the types of the fields in here:

builder.field("type", type);

Like: ("type", "text") or ("type", "long"), ("type", "date") ......

You can see the datatypes in here

I'll post @Mincong's comment as an answer because I was importing the wrong import that I found from github searchs:

What is the full name of your class "PutMappingRequest": org.elasticsearch.action.admin.indices.mapping.put.PutMappingRequest or org.elasticsearch.client.indices.PutMappingRequest? You should use the second one.
