使用JSON-SERDE将JSON数据导入Hive

Question

我正在尝试使用JSON-SERDE将以下JSON数据提取到Hive中，但出现错误。首先-此JSON数据有效吗？如果是，如何创建具有123456-123456值的agentId的这一列表。

{"agentId":{"string":"123456-123456"}}

CREATE EXTERNAL TABLE testingjson(
    agentId map <string>
)
ROW FORMAT SERDE 'org.apache.hive.hcatalog.data.JsonSerDe'
STORED AS TEXTFILE
LOCATION '/.../json_table';

  

编译语句时出错：失败：ParseException行4:20   输入类型不匹配的“>”期望值，在地图类型的“字符串”附近

Answer 1

是的，json有效。

尝试使用以下ddl和

如果您想要的值是123456-123456，则使用从testingjson中选择agentid ['string']；

        if (existingClaim.isPresent)
        {
            convertClaimFromDto(submittedClaim, existingClaim.get())
        } else {
