Gopal takes us through building up a Hadoop cluster via Kubernetes:
In our current scenario, we have 4 Node cluster where one is master node (HDFS Name node and YARN resource manager) and other three are slave nodes (HDFS data node and YARN Node manager)
In this cluster, we have implemented Kerberos, which makes this cluster more secure.
Kerberos services are already running in the different server which would be treated as KDC server.
In all of the nodes, we have to do a client configuration for Kerberos which I have already written in my previous blog. please go through below kerberos authentication links for more info.
Read on for the walkthrough.
