Hello @prabhat10 ,  Try this -    Backup your /etc/krb5.conf on all the hosts  Verify the encryption types supported from your Kerberos server (If MIT - Check "supported_enctypes" in /var/kerberos/krb5kdc/) Check the "Kerberos Encryption Types" under  CM > Administration > Security > Kerberos Credentials > Configuration. Include the encryption types supported by your KDC.  Enable "Manage krb5.conf through Cloudera Manager" from the same configuration page.  Select "Deploy Kerberos client configuration" from the drop-down near your cluster.  Once deployed, verify if the krb5.conf on the agent nodes have the encryption types included as mentioned in CM.  If CM server is running on stale kerberos configuration, copy the krb5.conf from one of the agent nodes to CM server. Regenerate the principals from CM. (If this is success, you should be able to restart CM and CDH services). ... View more
