Rafael commented on SPARK-26132:
--------------------------------

In release notes for Spark 3.0.0 they mentioned your ticket
{quote}Due to the upgrade of Scala 2.12, {{DataStreamWriter.foreachBatch}} is not source compatible for Scala program. You need to update your Scala source code to disambiguate between Scala function and Java lambda. (SPARK-26132)
{quote}
 

so maybe you know how we should use *foreachPartition* now in Scala code
{code:java}
dataFrame.foreachPartition(partition => {
  partition
    .grouped(Config.BATCH_SIZE)
    .foreach(batch => { 
     ....
     } 
}
{code}
Right now it call on any method like grouped, foreach cause the exception 
*value grouped is not a member of Object*
