在使用Spark SQL执行SQL任务的时候，由于Executor端报错如下，导致任务失败：
ERROR [FileFormatWriter:94]: Aborting job 474132a1-ea71-4615-932b-5c6d11325cf5. org.apache.spark.SparkException: Job aborted due to stage failure: Task 2250 in stage 6471.0 failed 10 times, most recent failure: Lost task 2250.9 in stage 6471.0 (TID 7355480) (bddwd-sys-rpm0681ff79.bddwd.baidu.com executor 61): java.io.InvalidClassException: org.apache.spark.sql.execution.TakeOrderedAndProjectExec; local class incompatible: stream classdesc serialVersionUID = 8146615053487733419, local class serialVersionUID = 2948812801925076513
