Ronan SY commented on BEAM-13610:
---------------------------------
I am sorry it seems that the issue has already been reported
> Conflict with Spark 3.1.2 scala version
> ---------------------------------------
>
> Key: BEAM-13610
> URL: https://issues.apache.org/jira/browse/BEAM-13610
> Project: Beam
> Issue Type: Bug
> Components: runner-spark
> Affects Versions: 2.34.0, 2.35.0
> Reporter: Ronan SY
> Priority: P2
>
> 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 ?
