Hadoop installation issue ubuntu 18.04: hadoop namenode -format error - hadoop

Question

I'm trying to do a hadoop installation.
I am following this article for hadoop installation instructions. One of the steps I need to do is to format the hadoop file system using the command:
root#ben-Aspire-E5-575G:~# hadoop namenode -format
I got the following error
2018-10-12 00:08:16,884 INFO namenode.NameNode: registered UNIX signal handlers for [TERM, HUP, INT]
2018-10-12 00:08:16,896 INFO namenode.NameNode: createNameNode [-format]

Answer 1

You're missing both </description> and a final </xml> outside of the end configuration tag in the file you've provided.
As the error says, there's a tag missing.
The description is optional, so feel free to delete that tag entirely

Answer 2

I think you have to fix the "description" tag. There is no proper end.
