（ Spark新手） 我在Linux机器上安装了独立的spark以进行POC。一切都很好看，我们的代码工作正常我们开始得到下面的间歇性错误：
ERROR SparkContext: Error initializing SparkContext.
java.nio.file.AccessDeniedException: /tmp/spark-8bcc1872-653b-419f-9d46-b3e449b3c223/userFiles-6ac82898-4415-4a93-9075-b50ace65ddc4/myscript.py
我厌倦了移动代码，重命名代码，简化了代码，但没有一个工作。在很短的时间内，错误就会自行停止。不，它不会去任何地方。
我的火花版本是spark-2.2.0 奇怪的是，一旦发生错误，当我键入pyspark时，它也无法以非常长的错误跟踪开始（在最后一部分下面）：

感谢帮助
答案 0 :(得分：0)
问题解决了。 umask设置导致metastore_db文件夹的权限不正确。 我不明白什么是正确的＆＃34;清洁＆＃34;命令提交pyspark而不在任何地方创建这些文件夹？
