elasticsearch - Elasticsearch:升级到7.9.3后无法创建索引(mapper_parsing_exception)

Question

我已经将群集从6.8升级到7.93，现在无法创建索引了
起初我以为我的默认映射有问题，但是即使没有指定映射也得到了mapper_parsing_exception

curl -X PUT localhost:9200/test-index?pretty

结果是

{
  "error" : {
    "root_cause" : [
      {
        "type" : "mapper_parsing_exception",
        "reason" : "Root mapping definition has unsupported parameters:  [_all : {enabled=false}]"
      }
    ],
    "type" : "mapper_parsing_exception",
    "reason" : "Failed to parse mapping [_default_]: Root mapping definition has unsupported parameters:  [_all : {enabled=false}]",
    "caused_by" : {
      "type" : "mapper_parsing_exception",
      "reason" : "Root mapping definition has unsupported parameters:  [_all : {enabled=false}]"
    }
  },
  "status" : 400
}

我意识到ES 7不再支持_all meta字段，这是我为ES 7计划的默认映射(使用它创建索引也不起作用)

{
  "mappings": {
    "properties": {
      "data": {
        "type": "text",
        "index": false
      },
      "metadata": {
        "type": "object",
        "properties": {
          "date": {
            "format": "strict_date_optional_time||epoch_millis",
            "type": "date"
          },
          "reception_date": {
            "format": "strict_date_optional_time||epoch_millis",
            "type": "date"
          },
          "source": {
            "type": "keyword"
          },
          "env": {
            "type": "keyword"
          },
          "type": {
            "type": "keyword"
          "filename": {
            "type": "text",
            "index": false
          "ts_ms": {
            "type": "long"
          },
          "ts": {
            "type": "long"
          }
        }
      }
    }
  }
}

我在docker中运行的PC上的测试实例上没有此错误。当我在测试实例上构建项目时，测试运行良好。它似乎仅在群集上特别失败。在集群上，存在ES 6指数。什么可能导致此映射错误？是否有可能是从ES 6继承的设置导致此问题？
这是我的日志中不太漂亮的java回溯

您可能拥有旧的索引模板，这些模板在创建新索引时会产生干扰。
尝试GET _template，看看是否有任何不兼容的映射参数可以更改以使其起作用。
最终，删除旧的未使用的模板。
