zncleon opened a new issue, #14251:
URL: https://github.com/apache/iceberg/issues/14251
### Apache Iceberg version
main (development)
### Query engine
Flink
### Please describe the bug 🐞
We are using the `DynamicIcebergSink`, `DynamicRecordGenerator` to collect
`DynamicRecord`(composed by `GenericRowData`), and we set `upsert` mode. It
works correctly at the beginning, but after running for a time, the following
problems may occur. What is the cause of this problem?
**StackTrace:**
```
java.lang.ClassCastException: class org.apache.iceberg.GenericDataFile
cannot be cast to class org.apache.iceberg.DeleteFile
(org.apache.iceberg.GenericDataFile and org.apache.iceberg.DeleteFile are in
unnamed module of loader 'app')
