apache-spark - 无法将文件写入齐柏林飞艇上的远程hdfs

Question

如何在Spark中将文件保存在HDFS服务器上

这是我的代码

csv_file.write.mode('overwrite').parquet('hdfs:///data/ifckp/docs/csv_files/cs')

这是我的错误:

Py4JJavaError: An error occurred while calling o3621.parquet.

Answer 1

这是一个简单的权限被拒绝错误。您从作为访问控制工具的游侠得到错误。要求您的hdfs管理员授予您写入要写入的目录或写入另一个目录的权限
