RestHighLevelClient 判断索引是否存在

private boolean isIndexExists(String indexName) {
    try {
    	GetIndexRequest getIndexRequest = new GetIndexRequest(indexName);
    	return restHighLevelClient.indices().exists(getIndexRequest, RequestOptions.DEFAULT);
    } catch (Exception e) {
    	log.error("check indexName occur error.", e);
    }
    return false;
}
