Elasticsearch _reindex/elasticsearch-dump不会复制源索引的所有字段 [英] Elasticsearch _reindex/elasticsearch-dump does not copy all fields of the source index

问题描述

我在Elasticsearch 6.x中有一个索引，我想将此索引复制到新的Elastic Search 7中.

I have an index in elasticsearch 6.x, I want to copy this index to new elastic search 7.

我尝试使用 elasticsearch-dump:v6.24.0 & _reindex API.我能够从源索引复制数据，但并非所有字段/属性都已被完全复制.似乎跳过了其中的几个.

I tried using elasticsearch-dump:v6.24.0 & _reindex api. I was able to copy the data from the source index, but not all the fields/properties are getting fully copied. It seems to skip few of them.

我要去哪里错了?

这是_reindex请求.

This is the _reindex request.

POST _reindex
{
  "source": {
    "remote": {
      "host": "http://prodsystem:9200"

    },
    "index": "file",
    "query": {
      "match_all": {}
    }
  },
  "dest": {
    "index": "filebkp"
  }
}
