      Description

      The reproduce code:

          sc.setCheckpointDir(checkpointDir)
          val c = sc.parallelize((1 to 1000)).map(_ + 1)
          c.count
          val dep = c.dependencies.head.rdd
          c.checkpoint()
          c.count
          assert(dep != c.dependencies.head.rdd)
      

      This limit is too strict , This makes it difficult to implement SPARK-3623 .
