[GitHub] [hudi] Limess commented on issue #4043: [SUPPORT] java.lang.ClassCastException: java.lang.String cannot be cast to org.apache.spark.sql.Row error when writing particular source data after column addition

   OK
   
   We got this to work again: we had to:
   
   1. Set `hoodie.datasource.write.reconcile.schema=false`
   2. Add the column to any new data. Without doing this, all the old data failed the schema validation step
   
   I'd assumed `hoodie.datasource.write.reconcile.schema=true` was soely capturing this use case so I don't understand why this fails here.
