DataWorks 为了搜索时忽略大小写，我在ElasticSearch中为name指定了normalizer：{"name":"name","normalizer":"lowercase_normalizer","type":"keyword"}。ODPS->ES导出的时候报错：ERROR ElasticSearchClient - PutMapping got ResponseCode: 400, ErrorMessage: {"root_cause":[{"type":"illegal_argument_exception","reason":"Mapper for [name] conflicts with existing mapper:\n\tCannot update parameter [normalizer] from [lowercase_normalizer] to [default]"}],"type":"illegal_argument_exception","reason":"Mapper for [name] conflicts with existing mapper:\n\tCannot update parameter [normalizer] from [lowercase_normalizer] to [default]"}？
