I need to commission a node in my secured cluster, I'm using MIT kerberos in my environment.Once I added, i need to make that newly added node as kerberised.
Kindly let me the step to follow or any links to follow.
If you chose to enable Kerberos using the Automated Kerberos Setup option, as part of the enabling Kerberos process, Ambari installs the Kerberos clients on the cluster hosts.
If your Cluster is already kerberized then you do not need to do anything special after adding the new node to it. Whatever components you will install to that newly added host ambari will make sure to add the kerberized configurations to it. Ambari should install the Kerberos client on that after adding the host , You can simply click on "Install Clients" on the "Hosts" page of the newly added host.
1. First install the kerberos workstation and client package on the host.
yum install krb5-workstation krb5-client
2. Copy the the kerberos config(/etc/krb5.conf) file to the new host.
3. Add the host choosing the proper template using Ambari
