我有一个Spark项目，最近很管用。
该项目获取一个CSV，并向其添加两个字段，然后使用saveasTextfile()输出JavaPairRdd的内容。
我的Spark版本是: 2.3.0我的java版本: 1.8
该项目在Windows10下的Eclipse IDE中运行。
这是错误：

我回答了我的问题：
最近，在对我有效之后，我在winutils.exe旁边的hadoop home hadoop.dll中添加了(运行另一个spark项目)。所以我删除了hadoop.dll，现在一切都好了

我也有相同的堆栈跟踪出现，但A.HADDAD的解决方案不起作用。我通过将我的hadoop版本( 2.6.0)更新到2.7.1来解决这个问题，因为它更接近我的spark安装(spark-2.3.2-bin-hadoop2.7)所指示的hadoop版本。

我收到了类似的错误，意识到我没有创建环境变量HADOOP_HOME，也没有使用HADOOP_HOME\bin更新Path变量
