[xgboost4j-spark] The program is  suspended at the step of cleaned accumulator.

I run the demo followed by the tutorial in https://xgboost.readthedocs.io/en/latest/jvm/xgboost4j_spark_tutorial.html
But it suspended at the step of "Cleaned accumulator 225".
What's the problem?
Spark version=2.3
Xgboost version=0.8
