]
Robert Levas updated AMBARI-13240:
----------------------------------
Description:
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}
was:
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 adding a property to {{kerberos-env}}, named
{{additional_kdc_hosts}}, to accept a comma-delimited list of hosts. If set,
the list of hosts are to be split where each {{additional_kdc_hosts}} item
generates an entry in the relevant realm block in the {{krb5.conf}} file. For
example:
{noformat:title=kerberos-env}
{
...
"kdc_host" : "kdc.example.com",
"additional_kdc_hosts" : "kdc1.example.com, kdc2.example.com"
...
}
{noformat}
{noformat:title=krb5.conf}
[realms]
EXAMPLE.COM = {
...
kdc = kdc.example.com
kdc = kdc1.example.com
kdc = kdc2.example.com
...
}
{noformat}
Note: the reason that {{additional_kdc_hosts}} is added rather than changing
{{kdc_host}} to {{kdc_hosts}} is to maintain backward compatibility.
