ElasticSearch index exists not working / reliable

Question

I am writing a simple Java wrapper around ElasticSearch\'s admin client. To test it I have a main method that first checks if an index exists (IndicesExistsRequest), if so delet

Answer 1

Here is my solution when using RestHighLevelClient client;

Here a code-snippet: :

public boolean checkIfIndexExists(String indexName) throws IOException {
            Response response = client.getLowLevelClient().performRequest("HEAD", "/" + indexName);
            int statusCode = response.getStatusLine().getStatusCode(); 
            return (statusCode != 404);
    }
