问题描述

我有一个Spark项目，该项目最近可以正常工作.

I have a Spark project that used to work lately .

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.

任何人都知道为什么我突然出现此错误吗?

any one knows why i get suddenly this error ?

推荐答案

我解决了我的问题:

在那之后我最近为我工作了，我将(运行另一个spark项目)放在Hadoop的家hadoop.dll中，并排在winutils.exe旁边. 所以我删除了hadoop.dll，现在一切都很好

After that worked for me lately i have put (to run another spark project) in the hadoop home hadoop.dll along side to winutils.exe. so i removed hadoop.dlland now everything is fine
