导出/导入索引时弹性转储不起作用

Question

我已经尝试使用elasticdump导出/导入索引。我有两个服务器，在服务器A上是elasticsearch版本5.4，在服务器B上是elasticsearch版本7.10。当我尝试使用elasticdump (2.2)时，我已经在服务器A上尝试过了：

elasticdump --input="http://xx.xxx.xxx.xx:9200/myindex" --output="http://xx.xxx.xxx.xx:9200/myindex" --type=data --searchBody '{"query": { "match_all": {} }, "stored_fields": ["*"], "_source": true }'

找到下面的最后几行：

Tue, 26 Jan 2021 08:19:20 GMT | got 100 objects from source elasticsearch (offset: 4900)
Tue, 26 Jan 2021 08:19:20 GMT | sent 100 objects to destination elasticsearch, wrote 0
Tue, 26 Jan 2021 08:19:20 GMT | got 100 objects from source elasticsearch (offset: 5000)
Tue, 26 Jan 2021 08:19:20 GMT | sent 100 objects to destination elasticsearch, wrote 0
Tue, 26 Jan 2021 08:19:20 GMT | got 100 objects from source elasticsearch (offset: 5100)
Tue, 26 Jan 2021 08:19:20 GMT | sent 100 objects to destination elasticsearch, wrote 0
Tue, 26 Jan 2021 08:19:20 GMT | got 32 objects from source elasticsearch (offset: 5200)
Tue, 26 Jan 2021 08:19:20 GMT | sent 32 objects to destination elasticsearch, wrote 0
Tue, 26 Jan 2021 08:19:20 GMT | got 0 objects from source elasticsearch (offset: 5232)
Tue, 26 Jan 2021 08:19:20 GMT | Total Writes: 0
Tue, 26 Jan 2021 08:19:20 GMT | dump complete

在另一端没有写入数据。我已经尝试在文件系统上写入转储(json格式)并导入它，结果相同。

你能帮帮忙吗？谢谢

最后，我使用了_reindex：

POST _reindex
{
  "source": {
    "remote": {
      "host": "https://REMOTE_ELASTICSEARCH_ENDPOINT:PORT",
      "username": "USER",
      "password": "PASSWORD"
    },
    "index": "INDEX_NAME",
    "query": {
      "match_all": {}
    }
  },
  "dest": {
    "index": "INDEX_NAME"
  }
}

它工作得很完美。非常感谢
