-------------------------------------
Summary: Kerberos: Allow multiple KDC hosts to be set while
enabling Kerberos
Key: AMBARI-13240
URL: https://issues.apache.org/jira/browse/AMBARI-13240
Project: Ambari
Issue Type: Bug
Components: ambari-agent, ambari-server, ambari-web
Affects Versions: 2.0.0
Reporter: Robert Levas
Assignee: Robert Levas
Priority: Minor
Fix For: 2.2.0
Because multiple KDCs may exist for an installation (failover, high
availability, etc...), Ambari should allow a user to specify multiple KDC hosts
to be set while enabling Kerberos and updating the Kerberos service's
configuration.
This should be done by allowing {{kerberos-env/kdc_host}} to accept a
(comma-)delimited list of hosts and then parsing that list properly when
building the krb5.conf file where each {{kdc_host}} item generates an entry in
the relevant realm block. For example:
{noformat:title=kerberos-env}
{
...
"kdc_hosts" : "kdc1.example.com, kdc2.example.com"
...
}
{noformat}
{noformat:title=krb5.conf}
[realms]
EXAMPLE.COM = {
...
kdc = kdc1.example.com
kdc = kdc2.example.com
...
}
{noformat}
