>             Project: Beam
>          Issue Type: Bug
>          Components: runner-spark
>    Affects Versions: 2.34.0, 2.35.0

> When trying to use Beam with spark 3.1.2 we are running into this issue :
> {code:java}
> InvalidClassException: scala.collection.mutable.WrappedArray {code}
> As explained here : [https://www.mail-archive.com/issues@spark.apache.org/msg297820.html]
> It's an incompatibility issue :  spark 3.1.2 is compiled with scala 2.12.10 but this issue is fixed only for scala >= 2.12.14.
>  
> It seems that this issue can be fixed :
> => either by compiling spark & beam with a scala version >= 2.12.14
> => either by upgrading the spark version used by beam to 3.2.0, which can be compiled with scala 2.13
>  
> Do you know if the switch to spark 3.2.0 is planned ?
