Apache spark “阿帕奇火花”；Py4JError:Java端的答案是空的；

我每次都会犯这个错误。。。 我用起泡水。。。 我的配置文件：

***"spark.driver.memory 65g
spark.python.worker.memory 65g
spark.master local[*]"***

数据量约为5 Gb。 没有关于此错误的其他信息。。。 有人知道为什么会这样吗？谢谢大家!

***"ERROR:py4j.java_gateway:Error while sending or receiving.

您是否尝试过在spark配置文件中设置

spark.executor.memory

和

spark.driver.memory
