需要帮助来推断NiFi中json文件的avro模式

我正在尝试在NiFi中创建一个流，该流采用有效的json文件，并使用PutHiveStreaming处理器将其直接放入配置单元表中。我的json如下所示：

{
"Raw_Json": {
    "SystemInfo": {
        "Id": "a string ID",
        "TM": null,
        "CountID": "a string ID",
        "Topic": null,
        "AccountID": "some number",
        "StationID": "some number",
        "STime": "some Timestamp",
        "ETime": "some Timestamp"
    },
    "Profile": {
        "ID": "ID number",
        "ProductID": "Some Number",
        "City": "City Name",
        "State": "State Name",
        "Number": "XXX-XXX-XXXX",
        "ExtNumber": null,
        "Unit": null,
        "Name": "Person Name",
        "Service": "Purchase",
        "AddrID": "00000000",
        "Products": {
            "Product": [{
                "Code": "CODE",
                "Description": "some description"

            },
            {
                "Code": "CODE",
                "Description": "some description"

            },
            {
                "Code": "CODE",
                "Description": "some description"

            },
            {
                "Code": "CODE",
                "Description": "some description"

            },
            {
                "Code": "CODE",
                "Description": "some description"

            },
            {
                "Code": "CODE",
                "Description": "some description"

            },
            {
                "Code": "CODE",
                "Description": "some description"

            },
            {
                "Code": "CODE",
                "Description": "some description"

            },
            {
                "Code": "CODE",
                "Description": "some description"

            },
            {
                "Code": "CODE",
                "Description": "some description"
            }]
        }
    },
    "Total": {
        "Amount": "some amount",
        "Delivery": "some address",
        "Estimate": "some amount",
        "Tax": null,
        "Delivery_Type": null

    }

},
"partition_date":"2017-05-19"

}

我正在使用InferAvroSchema处理器获取json，然后从那里通过使用推断的avro模式将json转换为avro格式，并将其发送到PutHiveStreaming处理器中。我的流程看起来像这样：

主要目标是我希望将所有“ Raw_Json”列都转储到配置单元表的一列中，并且该表将由“ partition_date”列进行分区，该列将成为表的第二列。问题是由于某种原因，NiFi在从“ Raw_Json”列中推断嵌套的json时遇到了问题，并且像表中的Null一样将其转储，如下所示：

有谁知道NiFi如何让NiFi将“ Raw_Json”列的整个嵌套Json读取为一列并将其发送到配置单元表？我该如何创建自己的avro模式？任何有关如何解决此问题的见解或想法将不胜感激！
