             Summary: Revisit TestCOWDataSourceStorage#testCopyOnWriteStorage
                 Key: HUDI-4239
                 URL: https://issues.apache.org/jira/browse/HUDI-4239
             Project: Apache Hudi
          Issue Type: Task
            Reporter: Rahil Chertara


Within the pr (Support Hadoop 3.x Hive 3.x and Spark 3.x) [https://github.com/apache/hudi/pull/5786,|https://github.com/apache/hudi/pull/5786] 

 

The testCopyOnWriteStorage has an issue with the test case where `nation` is added to the recordKeys. When debugging further it seems that this is due to an issue with avro 1.10.2 being used since it adds the following to the schema

```
"nation":"Canada"x
```

instead of adding

```
"nation": {
"bytes":"Canada"
}
```

This leads to the exception later for this test case since when nation is being retrieved from the record, since `getNestedFieldVal` expects the value to be nested as opposed to a String.
