java - Delete_by_query冲突继续进行在使用netty4的ElasticSearch 5.1.1中不起作用

Question

我已经在5.1.1版中编写了自己的内存中ElasticSearch服务器。它可以正确地添加文档，但无法删除。

Maven依赖项:

    <dependency>
        <groupId>org.elasticsearch</groupId>
        <artifactId>elasticsearch</artifactId>
        <version>5.1.1</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.elasticsearch.plugin</groupId>
        <artifactId>transport-netty4-client</artifactId>
        <version>5.1.1</version>
        <scope>test</scope>
    </dependency>

节点设置图:

    settingsMap.put("node.name", nodeName);
    settingsMap.put("path.conf", "target");
    settingsMap.put("path.data", "target");
    settingsMap.put("path.logs", "target");
    settingsMap.put("path.home", "target");
    settingsMap.put("http.type", "netty4");
    settingsMap.put("http.port", httpPort);
    settingsMap.put("transport.tcp.port", httpTransportPort);
    settingsMap.put("transport.type", "netty4");
    settingsMap.put("action.auto_create_index", "false");

一次删除多个文档的方法:

public boolean deleteType() throws IOException, CustomResponseException {
    String query = "{\n" + "  \"query\": {\n" + "    \"match_all\": {}\n" + "  }\n" + "}";
    HttpEntity entity = new NStringEntity(query, ContentType.APPLICATION_JSON);
    Response indexResponse = restClient.performRequest("POST",
            "/" + this.getIndex() + "/" + this.getType() + "/_delete_by_query?conflicts=proceed",
            Collections.<String, String>emptyMap(), entity);
    return processStatusCode(indexResponse.getStatusLine()) == 200;
}

运行测试时，出现错误:

org.elasticsearch.client.ResponseException: POST http://localhost:9205/testindexer/indexer/_delete_by_query?conflicts=proceed: HTTP/1.1 400 Bad Request {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"request [/testindexer/indexer/_delete_by_query] contains unrecognized parameter: [conflicts]"}],"type":"illegal_argument_exception","reason":"request [/testindexer/indexer/_delete_by_query] contains unrecognized parameter: [conflicts]"},"status":400}

另外，当我运行它而没有冲突进行时，得到的答案是创建了文档。为什么它的工作方式与此版本的文档不同？

这是我节点的状态:

{
  "name" : "indexernode",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "trP6UQg1SMKVyfR0qTEjYw",
  "version" : {
    "number" : "5.1.1",
    "build_hash" : "5395e21",
    "build_date" : "2016-12-06T12:36:15.409Z",
    "build_snapshot" : false,
    "lucene_version" : "6.3.0"
 },
 "tagline" : "You Know, for Search"
}

旁注:这不是删除所有索引数据的正确方法，但是我想您已经知道了。

您可以尝试在restclient中将参数作为参数而不是URL的一部分提供吗，jsut以确保这不是问题。

我认为这里的主要问题是，您说您正在运行自己的嵌入式版本的Elasticsearch(这就是您在内存中的意思)。您是否检查过reindex插件已安装该版本？
