Hi, Shani.
NameNode is a HDFS bottleneck, so running multiple namespaces within
only one NN is a risky. What do you want to achieve?
It might help you a bit - HDFS Federation

Hi,
I am Shani. I am currently doing a research on how to create multiple
namespaces within the sasme namenode.
I was looking at the code, and found some terms that I would like to have a
better understanding on.
1) What is a Namesystem?
2) If I could have guidance on where to look for namespace creation, it
would greatly help.
Any help is appreciated.
Regards,
Shani.
