Question

我有一个Spark项目，该项目最近可以正常工作。

该项目获取一个CSV，并向其中添加两个字段，然后使用saveasTextfile()输出 JavaPairRdd 的内容。

我的Spark版本为：2.3.0 我的Java版本：1.8

该项目在Windows 10下的Eclipse IDE中运行。

这是错误：

任何人都知道为什么我突然出现此错误吗？

Answer 1

我解决了我的问题：

最近为我工作了之后，我将（运行另一个Spark项目）放在了Hadoop的房子hadoop.dll中，并排在winutils.exe旁边。所以我删除了hadoop.dll，现在一切正常

Answer 2

我遇到类似的错误，意识到我没有创建环境变量HADOOP_HOME，并且Path变量未使用HADOOP_HOME \ bin更新

Answer 3

我有相同的堆栈跟踪出现，但是A.HADDAD的解决方案不起作用。我通过将hadoop版本（即2.6.0）更新为2.7.1来解决了该问题，因为它更接近于我的火花安装（spark-2.3.2-bin-hadoop2.7）所指示的hadoop版本。
