Apache Spark reassigned SPARK-38077:
------------------------------------
Assignee: Apache Spark
> Spark 3.2.1 breaks binary compatibility with Spark 3.2.0
> --------------------------------------------------------
>
> Key: SPARK-38077
> URL: https://issues.apache.org/jira/browse/SPARK-38077
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 3.2.1
> Reporter: Nadav Samet
> Assignee: Apache Spark
> Priority: Major
>
> [PR 35243|https://github.com/apache/spark/pull/35243] introduced a new
> parameter to class `Invoke` with a default value (`isDeterministic: Boolean =
> true`). Existing Spark libraries (such as
> [frameless|https://github.com/typelevel/frameless]) that invoke
> [Invoke|https://github.com/typelevel/frameless/blob/29961d549e332dddf5cd711ef699dde7460cc48a/dataset/src/main/scala/frameless/RecordEncoder.scala#L154]
> directly expect a method with 7 parameters, and the new version expects 8.
> If Frameless would recompile with Spark 3.2.1, the updated library will NOT
> be binary compatible with Spark 3.2.0. Adding default parameters to existing
> methods [should be
> avoided|https://github.com/jatcwang/binary-compatibility-guide#dont-adding-parameters-with-default-values-to-methods].
> One way forward would be to revert the change in the constructor and
> introduce a second constructor or a companion method that takes all the 8
> parameters.
