-------------------------------------------
Summary: Rename host and properly delete
Key: AMBARI-8887
URL: https://issues.apache.org/jira/browse/AMBARI-8887
Project: Ambari
Issue Type: Epic
Components: ambari-server
Affects Versions: 1.6.1
Reporter: Alejandro Fernandez
Assignee: Alejandro Fernandez
Fix For: 2.0.0
There are several issues associated with hosts.
* Uniquely identify a host. MAC address, IP are not sufficient. Perhaps store a
file so that even if the hostname changes on the same physical machine, the
rename can be auto-detected.
* Ability to rename: requires using FK from an primary ID that is not the
hostname, will require DB schema changes. When a host is readded, need to
consider what happens if the OS or environment changes.
* Properly delete a host (determine if we do hard-deletes that cascade across
all of the log records, or soft-deletes so that the hosts persist but not in
the cluster)
