Still hit this problem. Now I know how to reproduce this.
1. Write the iceberg table with the 0.10.0 version.
2. Read the iceberg table manifests with the 0.11.1 version.
The following code could fix the issue:
```
--- a/core/src/main/java/org/apache/iceberg/GenericPartitionFieldSummary.java
+++ b/core/src/main/java/org/apache/iceberg/GenericPartitionFieldSummary.java
@@ -121,7 +121,7 @@ public class GenericPartitionFieldSummary
@Override
public Boolean containsNaN() {
- return containsNaN;
+ return containsNaN == null || containsNull;
}
```
@RussellSpitzer @yyanyy, We may need to re-consider this with #2492 again.
