I am planning to migrate my existing MIT based Kerberos to AD based one for Cloudera distribution.
Is there any migration documentation available?
Based on what I have read from the Cloudera docs (cant find the link) the switch is not possible. You have to disable security Kerberos on the cluster ("reverting the steps" https://community.cloudera.com/t5/Cloudera-Manager-Installation/Disabling-Kerberos/td-p/19654) and then enable the security on the cluster again with AD.
But I would not do that, instead would deploy a new cluster and migrate data/users from the old one.
