我不能以某种方式使这个json进入 hive 表，要么成为所有null数据，要么无法被选择。我只需要DDL包含所有相同的字段，并且如果它是内部结构，我想让它作为字符串而不是尝试解析它。
唯一几乎只能通过hive-hcatalog-core-1.1.0-cdh5.10.0.jar实现的功能，因为某些数据为空白，
我可以用LIMIT查询，但是当我删除限制时，它返回了我这种错误org.apache.hadoop.hive.serde2.SerDeException: java.io.IOException: Field name expected
我的表创建:
ADD JAR hive-hcatalog-core-1.1.0-cdh5.10.0.jar;
CREATE EXTERNAL TABLE tabless (`dt` STRING, `hGeoLocation` STRING, `loginId` STRING, `hSearchFunnel` STRING, `timeseries` STRING, `locale` STRING, `fetcherResult` STRING, `searchType` STRING, `isBackDate` STRING, `hId` STRING, `hFrequency` STRING, `currency` STRING, `userType` STRING, `isSNA` STRING, `isBinding` STRING, `nodeId` STRING, `_id` STRING, `adjustedResult` STRING, `chosenProviderSell` STRING, `ChosenInventoryBeforeAdjusted` STRING, `PricingRules` STRING, `cInDate` STRING, `cOutDate` STRING, `machineId` STRING, `interface` STRING, `pricingSpec` STRING, `elapsedTime` STRING, `ChosenInventoryAfterAdjusted` STRING, `chosenProviderBase` STRING, `fFrequency` STRING, `kafkaPT` STRING, `kafkaST` STRING, `cookieId` STRING, `sessionId` STRING,`pricingSpecAbPriceAdjustment` STRING,`searchId` STRING,`prevSearchId` STRING, `competitorRequest` STRING, `CPricingRule` STRING, `CStatisticChosenMethod` STRING, `ChosenCId` STRING, `ChosenCPricingRule` STRING, `chosenCPriceType` STRING, `CPriceDiff` STRING, `competitorResponse` STRING, `searchRateType` STRING) COMMENT 'somecomment'

请根据需要使用在线json解析器，
我的JSON看起来像这样:
