----------------------------------
Summary: Add datanode to Ozone failed to start due to kdc and
admin_server entry in krb5.conf was not updated
Key: HDDS-6530
URL: https://issues.apache.org/jira/browse/HDDS-6530
Project: Apache Ozone
Issue Type: Bug
Components: Ozone Datanode
Reporter: George Huang
Adding new datanode to Ozone on a secured cluster with kerberos and TLS.
Datanode failed to start after assigning Ozone datanode role. In particular if
entries of kdc and admin_server in krb5.conf contains old value point to some
other random host. The old value was not updated to reflect the newly assigned
Ozone DN role in the new cluster.
The result was DN failed to start. The expectation is corresponding entries in
krb5.conf on these nodes got updated when assigned DN role for Ozone.
