elasticsearchwriter对 es7.9.2 版本column映射不生效

使用datax elasticsearchwriter往 es 7.9.2 版本写入数据，column配置没有生效
elasticsearch版本7.9.2
datax配置:
"writer": {
"name": "elasticsearchwriter",
"parameter": {
"endpoint": "http://XXX:9200",
"accessId": "xxxx",
"accessKey": "xxxx",
"index": "XXXX",
"type": "_doc",
"cleanup": true,
"settings": {"index": {"number_of_shards": 1, "number_of_replicas": 0}},
"column": [
{"name": "company_id", "type": "integer"},
{ "name": "company_nm","type": "text" },
{ "name": "is_list","type": "integer" },
{ "name": "list_type","type": "integer" },
{ "name": "is_new_otc","type": "integer" },
{ "name": "is_bond","type": "integer" },
{ "name": "is_finance","type": "integer" },
{ "name": "fin_type","type": "integer" },
{ "name": "fin_type_supp","type": "text" },
{ "name": "is_itfin","type": "integer" },
{ "name": "is_del","type": "integer" },
{ "name": "create_dt","type": "date", "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"},
{ "name": "updt_dt","type": "date", "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"}
],
"discovery": false,
"dynamic": false,
"batchSize": 1000
}
}
}

最终生成的映射中column配置都没有生效，全量使用的是es默认mapping，特别是日期格式

Start at the elasticsearchwriter entry point and reproduce the issue with the supplied Elasticsearch 7.9.2 configuration. Compare the generated index mapping with the column definitions, especially the date format and integer/text types; done means the configured mapping is applied instead of Elasticsearch defaults.
