------------------------------------------
Summary: Create a script to change host names for a stopped cluster
Key: AMBARI-13507
URL: https://issues.apache.org/jira/browse/AMBARI-13507
Project: Ambari
Issue Type: Task
Components: ambari-server
Affects Versions: 2.1.3
Reporter: Vitaly Brodetskyi
Assignee: Vitaly Brodetskyi
Priority: Critical
Fix For: 2.1.3
At a high-level we may follow this approach:
Ensure cluster is not kerberized
Assume all services to be stopped (add a check to ensure that services are
stopped)
We may also need to check and confirm that there are no commands pending
execution - or just mark them as aborted
Update all host names in the database based on the mapping provided (e.g. host1
--> master01.dev.com)
As SQLClient cannot be assumed consider using jdbc - similar to the Upgrade code
Modify all configs to replace the hostnames as needed (not sure if plain search
and replace will suffice)
Agents need to be re-configured if ambari-server hostname changes
