      When building cubes, there is an error 'ConcurrentModificationException' thrown by Spark, but it does not impact the building job.

      https://issues.apache.org/jira/browse/SPARK-34731

      Fixed PR: https://github.com/apache/spark/pull/31826 

      So It needs to upgrade Spark 3.X version to 3.1.2
