Realm name considerations for replication policies

If the source and destination clusters each use Kerberos for authentication, you must consider the realm names before you create a replication policy.

Use one of the following configurations to prevent conflicts when running replication jobs:
  • If the clusters do not use the same KDC (Kerberos Key Distribution Center), Cloudera recommends that you use different realm names for each cluster.
  • You can use the same realm name if the clusters use the same KDC or different KDCs that are part of a unified realm, for example where one KDC is the master and the other is a worker KDC.
