elasticsearch - Elastic Search不允许我索引先前设置为false的新模板版本中的字段

Question

我有一个包含很多字段的模板，下面是一个简短的示例。

{
  "index_patterns": "test*",
  "order": 2,
  "version": 2,
  "aliases": {
    "tests": {

    }
  },
  "settings": {
    "number_of_shards": 5,
    "analysis": {
      "normalizer": {
        "lowercase_normalizer": {
          "type": "custom",
          "char_filter": [

          ],
          "filter": [
            "lowercase"
          ]
        }
      }
    }
  },
  "mappings": {
    "dynamic": "false",
    "properties": {
      "id": {
        "type": "keyword",
        "normalizer": "lowercase_normalizer"
      },
      "emailAddress": {
        "enabled": false
      },
      "createdTimestampEpochInMilliseconds": {
        "type": "date",
        "format": "epoch_millis"
      },
      "updatedTimestampEpochInMilliseconds": {
        "type": "date",
        "format": "epoch_millis"
      },
      "createdDate": {
        "type": "date"
      },
      "updatedDate": {
        "type": "date"
      }
    }
  }
}

字段 emailAddress设置为 enabled=false，我们需要使其可搜索，因此我们需要更改模板并像 id字段一样设置此字段类型和规范化器。然后放入模板，并将数据从索引 test-2重新索引到索引 test-4。

{
  "index_patterns": "test*",
  "order": 4,
  "version": 4,
  "aliases": {
    "tests": {

    }
  },
  "settings": {
    "number_of_shards": 5,
    "analysis": {
      "normalizer": {
        "lowercase_normalizer": {
          "type": "custom",
          "char_filter": [

          ],
          "filter": [
            "lowercase"
          ]
        }
      }
    }
  },
  "mappings": {
    "dynamic": "false",
    "properties": {
      "id": {
        "type": "keyword",
        "normalizer": "lowercase_normalizer"
      },
      "emailAddress": {
        "type": "keyword",
        "normalizer": "lowercase_normalizer"
      },
      "createdTimestampEpochInMilliseconds": {
        "type": "date",
        "format": "epoch_millis"
      },
      "updatedTimestampEpochInMilliseconds": {
        "type": "date",
        "format": "epoch_millis"
      },
      "createdDate": {
        "type": "date"
      },
      "updatedDate": {
        "type": "date"
      }
    }
  }
}

当尝试使用Elastic Search ReindexOnServer重新索引或手动查询数据并从一个索引移到另一个索引时，我们会收到 400 Bad Request错误。

{
  "index": "test-4",
  "type": "_doc",
  "id": "54e1ea11-d7b4-4310-90f1-11ddbecc4d21",
  "cause": {
    "type": "mapper_parsing_exception",
    "reason": "Failed to parse mapping [_doc]: Mapping definition for [emailAddress] has unsupported parameters:  [enabled : false]",
    "caused_by": {
      "type": "mapper_parsing_exception",
      "reason": "Mapping definition for [emailAddress] has unsupported parameters:  [enabled : false]"
    }
  },
  "status": 400
}

错误消息有点令人困惑，更改模板版本应使用最新的模板自动创建索引，并遵守新的字段索引类型和规范化器。
不知道我在这里想念什么。

我将删除旧模板，因为它对您不再有用。 version字段仅供引用，ES不使用。

这是因为order设置导致两个模板都启动并且最新模板(v4)覆盖了旧模板(v2)。但是，不再支持enabled设置，这会导致此错误。如果删除较旧的模板，就可以了。
