> Issue Type: Bug
> Reporter: yanxiang
> Priority: Major
> Fix For: 0.11.0

>
> the first read result is incorrect when Flink upsert- Kafka connector is used in HUDi .
>
> ETL path: flink upsert-kafka connector -> hudi table (MOR table,query by stream)
>
> Here is the case:
>
> 1. the first time: write two records with the same primary key into kafka, and insert them into hudi table. the query result should be three records: +I first record, -U first record, +U second record; But the first time I query hudi table, I found that all the data operation were +I: +I first record,+I first record and +I second record, and there was no update operation;
> Three times +I has affected hudi's subsequent ETL process-the data of groupBy is inaccurate;
> 2. Second time: Exit the first query, restart the query job of hudi table, and the query results are normal: +I first data, -U first data, +U second data.
>
> Reason:
> Reason:There is a bug in the program. When no data log file is generated, the Schema does not include the column' _ hoodie _ operation'.Please refer to the following link for details：
