Elasticsearch 重新索引错误 - 客户端请求超时

问题描述 投票:0回答:2

我正在尝试使用以下行重新索引:

POST _reindex
{
  "source": {
    "index": "poi_201705"
  },
  "dest": {
    "index": "poi_dev_2"
  }
}

但是我在 kibana 控制台中收到以下错误:

{
  "statusCode": 504,
  "error": "Gateway Time-out",
  "message": "Client request timeout"
}

任何人都可以告诉我这是什么问题以及如何解决它。

504 只是表示请求仍在运行,但从 Kibana 到 ES 的 HTTP 连接超时。

您仍然可以使用任务管理 API 来查看正在进行的请求,如下所示:

GET _tasks?actions=*reindex&detailed

如果您想异步运行任务,也可以使用以下命令来完成:

POST _reindex?wait_for_completion=false

这将返回一个任务 ID,然后可以通过以下方式检查其进度:

GET _tasks/<task-id>

  • 要查看您的索引,您可以在 Kibana 开发工具中检查
    GET _cat/indices/source_index,destination_index
    API 调用结果。
  • 通过
    GET source_index,destination_index/_count
    API 比较文档数量。

为了防止

504 Gateway Time-out Client request timeout
错误,您可以使用
?wait_for_completion=false

如果请求包含wait_for_completion=false,Elasticsearch 执行一些预检检查,启动请求,并返回 您可以使用任务来取消或获取任务的状态。 Elasticsearch 创建此任务的记录作为文档,位于 _任务/https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-reindex.html#docs-reindex-task-api

POST _reindex?wait_for_completion=false
{
  "conflicts": "proceed",
  "source": {
    "index": "kong-01"
  },
  "dest": {
    "index": "kong-01-new"
  }
}

回复:

{
  "task": "Djf3dFpkQle-dqjG0sf6tw:45922151"
}

检查重建索引过程:

GET _tasks/Djf3dFpkQle-dqjG0sf6tw:45922151

任务 API 调用的输出示例:
