当我将pyspark Dataframe保存为拼花地板文件时，出现以下错误：

Py4JJavaError: An error occurred while calling o50.parquet.

原因是什么？我如何克服这个错误

我正在使用Pyspark 2.3.0

数据帧大约有2亿行

以下是运行spark的配置

pyspark--num executors 20--executor内存8G --执行器内核5—驱动程序内存10G—驱动程序内核3

---

UnsupportedOperationException听起来像是出现了版本不匹配错误。您应该确认您正在使用的spark版本是根据您正在使用的Hadoop的相同版本构建的

有关spark版本，请查看您从spark网站下载的内容。它们提供了为Hadoop2.7和Hadoop2.6构建的不同二进制文件

对于hadoop版本，可以运行以下命令：

hadoop version

---

你能提供代码和数据示例吗？我安装了spark 2.3和Hadoop 2.8.3
