Example 1 with MetadataFeature

use of org.apache.sdap.mudrod.recommendation.structure.MetadataFeature in project incubator-sdap-mudrod by apache.

the class NormalizeFeatures method normalizeMetadataVariables.

public void normalizeMetadataVariables(ESDriver es) {
    es.createBulkProcessor();
    SearchResponse scrollResp = es.getClient().prepareSearch(indexName).setTypes(metadataType).setScroll(new TimeValue(60000)).setQuery(QueryBuilders.matchAllQuery()).setSize(100).execute().actionGet();
    while (true) {

            Map<String, Object> metadata = hit.getSource();
            Map<String, Object> updatedValues = new HashMap<>();
            // !!!important change to other normalizer class when using other metadata
            MetadataFeature normalizer = new PODAACMetadataFeature();
            normalizer.normalizeMetadataVariables(metadata, updatedValues);
            UpdateRequest ur = es.generateUpdateRequest(indexName, metadataType, hit.getId(), updatedValues);
            es.getBulkProcessor().add(ur);
