>                 Key: HUDI-2812
>                 URL: https://issues.apache.org/jira/browse/HUDI-2812
>             Project: Apache Hudi
>          Issue Type: Bug
>            Reporter: Alexey Kudinkin
>            Assignee: Alexey Kudinkin
>            Priority: Major
>
> Current version of Apache Parquet is from 2 years old and contains at least one known race-condition that might be compromising correctness of the \{{DateType}}:
>  
> Current version of 1.10 (and seems like 1.11 as well) contains {{DateStringifier class that uses *static shared* {{SimpleDataFormat}}}} object which is known to be NOT thread-safe.
> Therefore any access to that object (for example upon serialization) exposes use to RCs.
