I am in a databasing class at school and my professor is having us work with hadoop v3.2.1. In following a youtube tutorial to install on windows, I am stuck on the formatting namenode part. this is what comes up in cmd:

and i was following this tutorial: How to Install Hadoop on Windows until about halfway through when i realized it was too old and then switched to this one: How to Install Hadoop 3.2.0 in Windows10
Also, I have no idea if this is related to my current problem, so I will say this. When I skip to the next step and type start-all, resource manager and node manager both error out. Figured I'd stuff it all into one question.
The following error is a Bug in Hadoop 3.2.1.
This issue will be solved within the next release. For now, you can fix it temporarily using the following steps:
hadoop-hdfs-3.2.1.jar
file from the following link.hadoop-hdfs-3.2.1.jar
to hadoop-hdfs-3.2.1.bak
in folder %HADOOP_HOME%\share\hadoop\hdfs
hadoop-hdfs-3.2.1.jar
to folder %HADOOP_HOME%\share\hadoop\hdfs
