Thank you, everyone. I had the same issue, and it was resolved after using the proper winutils version for Spark 4.0.0/Hadoop 3.4.x. You can download it from https://github.com/kontext-tech/winutils/tree/master

1. Copy the entire bin from hadoop-3.4.0-win10-x64

2. Paste in C:\Hadoop (it will look like C:\Hadoop\bin)

3. Add variable HADOOP_HOME = C:\Hadoop

4. Add Path C:\Hadoop\bin

5. Optional (If above doesn't work) - Add hadoop.dll to C:\Windows\System32 (Suggested by 1 of the commenters on this post)
