Java RestHighLevelClient put mapping manually

Onoxider · January 18, 2018, 3:29pm

Hello,

is there any way to put mapping with RestHighLevelClient?

I know that it's possible with TransportClient via this Doc page:
https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-admin-indices.html

But as for RestHighLevelClient I haven't found any information.

Best regards

Добрый день!

Подскажите, пожалуйста, есть ли возможность задать маппинг через RestHighLevelClient?
ну или хотя бы через low level client.

с уважением,

In one of the next versions 6.x, it looks like it will be possible to use the CreateIndex API call which will allow to set a mapping at index creation time:

Yeah. And here is how I'm doing it in the mean time:

github.com

dadoonet/fscrawler/blob/master/elasticsearch-client/src/main/java/fr/pilato/elasticsearch/crawler/fs/client/ElasticsearchClient.java#L76-L106


/**
 * Create an index
 * @param index index name
 * @param ignoreErrors don't fail if the index already exists
 * @param indexSettings index settings if any
 * @throws IOException In case of error
 */
public void createIndex(String index, boolean ignoreErrors, String indexSettings) throws IOException {
    logger.debug("create index [{}]", index);
    logger.trace("index settings: [{}]", indexSettings);
    try {
        StringEntity entity = null;
        if (!isNullOrEmpty(indexSettings)) {
            entity = new StringEntity(indexSettings, ContentType.APPLICATION_JSON);
        }
        Response response = getLowLevelClient().performRequest("PUT", "/" + index, Collections.emptyMap(), entity);
        logger.trace("create index response: {}", LowLevelClientJsonUtil.asMap(response));
    } catch (ResponseException e) {
        if (e.getResponse().getStatusLine().getStatusCode() == 400 &&
                (e.getMessage().contains("index_already_exists_exception") || // ES 5.x

I'm sorry, I forgot to mention that the version I'm using is 6.1, so it's better to get to 6.x since it has more features?

val · January 19, 2018, 9:17am

6.x is not released yet that was just a link to documentation of the next future release.

Onoxider · January 19, 2018, 10:39am

Yes, 6.1 is the current and it doesn't have CreateIndex API

By the way, for some reason gradle dependency is not working i.e. after ptting the following dependency no packages are being added to the project:

compile 'org.elasticsearch.client:elasticsearch-rest-high-level-client:6.2.0'

val · January 19, 2018, 10:42am

Normal since 6.2 is not released yet

You can inspire yourself from the code @dadoonet provided earlier, that should do the trick

Onoxider · January 19, 2018, 10:44am

Thank you, I'll look through it.

You are doing a workaround by getting lowlevelclient and performing basic http requests to put mapping, am I correct?

Onoxider · January 19, 2018, 10:46am

Yeah, apparently this is only way to do.

So, to sum up, there's no way in current stable version(6.1) to put mapping via High Level Client only, right?

val · January 19, 2018, 10:49am

Correct. As far as I know.
