Some issues regarding HDFS federation

["hehaoreset@gmail.com" <he...@gmail.com>]

Hello.

I have a version 3.3.4 Hadoop cluster with over a thousand datanodes. I want
to use HDFS Router based Federation. May I ask you a few questions.

The first question is, is it better to deploy the router on the namenode
server or separately? I want to add a set of Namenodes to the existing HDFS
cluster, which means there are two namespaces.

The second question is that I have used Kerberos, and federation can run
normally. When the value of hadoop.http.authentication.type is kerberos, when
I access the router's HTTP page, it shows that a username and password are
required. How is this set?

  
  

I have read the introduction to Federation on the Hadoop version 3.3.4 page.
If you have any other information, could you please recommend it.

  
  

Thank you for reading.
