**Search before asking** - [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar. **Paimon version** master @ a5e87ebf6 (2.1-SNAPSHOT) **Compute Engine** Hive **Minimal reproduce step** 1. Create a Paimon table with a `BLOB` column and write one row. 2. Read it from Hive: `SELECT * FROM t;` The query always fails with: ``` java.lang.ClassCastException: org.apache.paimon.data.BlobData cannot be cast to [B ``` `PaimonObjectInspectorFactory.create()` groups `case BLOB:` with `BINARY`/`VARBINARY` and returns Hive's `JavaBinaryObjectInspector`, whose `getPrimitiveJavaObject` casts its input to `byte[]`. The read path hands it a `Blob` instead: `InternalRow.createFieldGetter` maps `case BLOB:` to `row.getBlob(pos)`. The Spark connector (`DataConverter`, `((Blob) o).toData()`) and the Flink connector (`FlinkRowDataWithBlob`) already convert at the engine boundary; Hive is the only one missing it. **What doesn't meet your expectations?** Expected: reading a BLOB column from Hive returns its binary content. Actual: every such query fails with `ClassCastException`. **Anything else?** Introduced by #8070, whose tests only feed `byte[]` directly, so the defect was never exercised. **Are you willing to submit a PR?** - [x] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
