I have setup single node HDP2.6 deployed using Ambari.
My single node hostname is nhknox-Virtual-Machine.mad.lab
I have KDC server setup at Domain Controller as Active Directory Domain Services.
Now I am enabling Kerberos, which is going through fine. Then, on ambari wizard it stopping all the services, which is fine too. Then, it is trying to start all the services after kerberized hadoop.
There my Namenode is not starting and below are the logs for the same. Please suggest for the solution
