FE 和 BE 节点正常，使用 Doris on es ，不能正确链接至 ES 地址

[xlz926]

环境：docker 容器内容部署好单节点 BE 和 FE节点，ES 访问也是正常的，链接至扩展ES 地址,建表语句：

CREATE EXTERNAL TABLE test (
k1 bigint(20) COMMENT "",
k2 datetime COMMENT "",
k3 varchar(20) COMMENT "",
k4 varchar(100) COMMENT "",
k5 float COMMENT ""
) ENGINE=ELASTICSEARCH
PROPERTIES (
"hosts" = "http://172.17.0.1:9200",
"index" = "test",
"type" = "_doc",
"user" = "root",
"password" = "",
"enable_docvalue_scan" = "true"
);
创建语句正常执行成功，hosts 地址如果正确，但是查询的时候 Ip 地址为什么会是72.20.0.2 ，具体错误日志如下：
I0214 11:49:27.722384 15681 task_worker_pool.cpp:1098] finish report task. master host: 172.17.0.2 port: 9020

访问 ES 的地址变成了 172.20.0.2 这个 IP 地址。我试着把 ES 地址改为一个不可用地址会提示如下错误：
1064 - errCode = 2, detailMessage = fetch es table [test] metadata failure: Failed to connect to /172.17.0.2:9200, Time: 0.002000s

请问是否还有配置还是哪里设置不对，怎么解决 ES 的正常访问

[wuyunfeng]

Doris会去探测数据所在的节点，你建表的时候配置的地址是用来获取元数据信息的，通过元信息会得到数据分布的节点列表，然后直接去对应的节点上请求

#5324

[xlz926]

以上问题，如果我直接把 target 写成访问172.17.0.1:9200 地址，查询的时候就正常了，没有以上异常。请问下 这个 target 是在配置文件中可以配置吗，我看代码目前是默认就把本机做为访问节点的。

不能手动配置哈，你的ES前面是不是有一个代理啊？Doris是不是没法访问ES的数据节点，如果是这样的话得看这个PR了：#5325

@wuyunfeng Hi, I faced the same question, doris vesion 0.14. Table DDL：

CREATE EXTERNAL TABLE `gch_test_es` (
  `k1` bigint(20) COMMENT "",
  `k2` datetime COMMENT "",
  `k3` varchar(20) COMMENT "",
  `k4` varchar(100) COMMENT "",
  `k5` float COMMENT ""
) ENGINE=ELASTICSEARCH
PROPERTIES (
"hosts" = "http://10.50.253.1:9200,http://10.50.253.2:9200,http://10.50.253.3:9200,http://10.50.253.4:9200,http://10.50.253.5:9200,http://10.50.253.6:9200,http://10.50.253.7:9200",
"index" = "test1",
"type" = "_doc",
"user" = "",
"password" = ""
);

Some error messages appear in the be.log:

Why es request url looks like this, so confused.

@ddsr-ops same question， do you solve now ?

[wuyunfeng]

@ddsr-ops datanode1/10.50.253.1:9200/test1/_doc/_search 确认下这个吧 地址不对

[ddsr-ops]

@ddsr-ops same question， do you solve now ?

@slowmoon yes, add network.host = 0.0.0.0 in es yml config file, then restart es and recreate doris table , you can solve it .

[ddsr-ops]

@ddsr-ops datanode1/10.50.253.1:9200/test1/_doc/_search 确认下这个吧 地址不对

@wuyunfeng I believe you have seen the ddl of table gch_test_es, I config hosts correctly. But I add network.host = 0.0.0.0 in es yml config file, restart es, then doris could connect es successfully.

[wuyunfeng]

嗯 我的意思是地址前面有个datanode1，改成0.0.0.0可以说明还是网络问题呢
