Geoffrey, My cluster continues to run with cached credentials from AD but issues with Ranger since AD is gone. I was using AD as the KDC for the entire cluster. It is a 7 node cluster which is completely Kerberized with main Ambari infrastructure node + dual masternodes for HA namenodes + 3 worker nodes + 1 edge node with Ranger/Knox/Zeppelin installed. Rick

I have an Kerberized HDP Cluster 2.6.4 integrated with Active Directory using Ranger LDAP and KNOX-LDAP. Typical lab environment in which AD has crashed with no way to recover so all the AD/Kerberos integration is gone. Question: What is the best way to recover without rebuilding the HDP cluster? Thanks Rick
