Setting up Authentication-Kerberos in Open-Source Self Managed 5 node cluster

[#1]

I have 5 Nodes:

• NN1
• NN2
• DN1
• DN2
• DN3

Three Apache Services:

• Zookeeper
• Hadoop
• Yarn
• HBase

Will need MapRed too

For authentication-Companywide my client is using LDAP, AD. For application purpose they setup Kerberos and Active Directory as KDC.
So, its AD Kerberos. I don't handle KDC by myself - Security team does.

Currently I have setup an open-source self-managed Hadoop cluster and its configured to 'SIMPLE AUT'

I want to use the authentication, so how do i proceed sir? Can someone please help with detailed steps and instruction?

Hi @therealsrikanth 

I understand you want to enable Kerberos authentication in an open-source Hadoop cluster.

Please refer to the following document to configure Kerberos authentication.
