> Spark Avro SerDe returns wrong result upon multiple calls

> Key: HUDI-4915
> URL: https://issues.apache.org/jira/browse/HUDI-4915
> Project: Apache Hudi
> Issue Type: Bug
> Components: spark
> Reporter: Yann Byron
> Priority: Critical
> Labels: pull-request-available
> Fix For: 0.12.1
>
>
> Currently, Spark Avro serializer/deserializer has a bug that it will return
> the same object when we call this method twice continuously. For example:
> val row1: InternalRow = ...
> val row2: InternalRow = ... // record2 is different with record1
>
> val serializeredRecord1 = serialize(row1)
> val serializeredRecord2 = serialize(row2)
> serializeredRecord1.equals(serializeredRecord2)
>
> That is because we use the `val` to declare the serializer/deserializer
> methods, so the latter's result will cover the previous one.
