我是一个新手Flink，我试图发挥ElasticSearch连接器，但没有成功。我在docker上安装了elasticsearch 5.5、kibana和flink 1.4。
这是我的密码：

<dependencies>
    <dependency>
        <groupId>org.apache.flink</groupId>
        <artifactId>flink-clients_2.11</artifactId>
        <version>1.4.0</version>
    </dependency>
    <dependency>
        <groupId>org.apache.flink</groupId>
        <artifactId>flink-java</artifactId>
        <version>1.4.0</version>
    </dependency>
    <dependency>
        <groupId>org.apache.flink</groupId>
        <artifactId>flink-streaming-java_2.11</artifactId>
        <version>1.4.0</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.flink</groupId>
        <artifactId>flink-connector-rabbitmq_2.11</artifactId>
        <version>1.4.0</version>
    </dependency>
    <dependency>

        <artifactId>flink-connector-elasticsearch5_2.11</artifactId>
        <version>1.4.0</version>
    </dependency>
</dependencies>

java代码是：

DataStream<String> consumer = .....

    consumer.print();

    Map<String, String> config = new HashMap<>();
    config.put("cluster.name", "docker-cluster");
    config.put("bulk.flush.max.actions", "1");

    List<InetSocketAddress> transports = new ArrayList<>();
    transports.add(new InetSocketAddress("127.0.0.1", 9300));

    consumer.addSink(new ElasticsearchSink<>(config, transports, new ElasticsearchSinkFunction<String>() {
        public IndexRequest createIndexRequest(String element) {
            Map<String, String> json = new HashMap<>();
            json.put("id", "2");
            return Requests.indexRequest()
                    .index("signinindex").type("signin").source(json);
        }

        public void process(String element, RuntimeContext ctx, RequestIndexer indexer) {
            indexer.add(createIndexRequest(element));
        }
    }));

    env.execute();

但是当我尝试在ide中提交一个新作业时，它似乎一直在等待，所以我想知道ElasticSearch5.5是否存在一些与flink冲突的问题。谢谢。
[更新]：我用es 5.1.2做了一些测试，现在在提交我的jar时收到以下异常（我也尝试用所有连接器将flink升级到1.4.1）：

显然主要方法是存在的。
