[GitHub] [iceberg] huleilei opened a new issue, #5878: Core: Serialize the params in Blob
huleilei opened a new issue, #5878:
URL: https://github.com/apache/iceberg/issues/5878
### Apache Iceberg version
0.14.1 (latest release)
### Query engine
Spark
### Please describe the bug 🐞
Using Spark to gen `Blob` for every DataFile, I meet a problem:
```
org.apache.spark.SparkException: Job aborted due to stage failure: task 19.0 in stage 1.0 (TID 20) had a not serializable result: org.apache.iceberg.puffin.Blob
Serialization stack:
- object not serializable (class: org.apache.iceberg.puffin.Blob, value: org.apache.iceberg.puffin.Blob@23c56e35)
- writeObject data (class: java.util.ArrayList)
- object (class java.util.ArrayList, [org.apache.iceberg.puffin.Blob@23c56e35])
```
In the `Blob`, the content in constructor is
```
public Blob(
String type,
List<Integer> inputFields,
long snapshotId,
long sequenceNumber,
ByteBuffer blobData,
@Nullable PuffinCompressionCodec requestedCompression,
Map<String, String> properties) {
Preconditions.checkNotNull(type, "type is null");
Preconditions.checkNotNull(inputFields, "inputFields is null");
Preconditions.checkNotNull(blobData, "blobData is null");
Preconditions.checkNotNull(properties, "properties is null");
this.type = type;
**this.inputFields = ImmutableList.copyOf(inputFields);**
this.snapshotId = snapshotId;
this.sequenceNumber = sequenceNumber;
this.blobData = blobData;
this.requestedCompression = requestedCompression;
**this.properties = ImmutableMap.copyOf(properties);**
}
```
