Add mappings to an Elasticsearch index in realtime
Changing mapping on existing index is not an easy task. You may find the reason and possible solutions in here:
http://www.elasticsearch.org/blog/changing-mapping-with-zero-downtime/
to get current mapping details, here is the sample code:
Put Mappings In Real time:private void putMapping() { if (client != null) { if (client.admin().indices().prepareExists(IndexName).execute().actionGet().isExists()) { XContentBuilder mappings = null; try { mappings = XContentFactory.jsonBuilder().startObject() .startObject(INDEX_TYPE) .startObject("properties").startObject(FIELD_NAME) .field("type","string") .field("store","yes") .field("index", "analyzed") .field("analyzer", "simple").endObject() .endObject() .endObject().endObject(); } catch (IOException e) { e.printStackTrace(); } client.admin().indices().prepareClose(IndexName).execute().actionGet(); client.admin().indices().prepareDeleteMapping(IndexName).setType(INDEX_TYPE).execute().actionGet(); client.admin().indices().preparePutMapping(IndexName).setIgnoreConflicts(true).setType(INDEX_TYPE).setSource(mappings).execute().actionGet(); client.admin().indices().prepareOpen(IndexName).execute().actionGet(); } } else {throw new IllegalStateException(" Elastic Search not initialized properly.."); }}
