Today Elasticsearch accepts, but silently ignores, port ranges in the `discovery.seed_hosts` setting: ``` discovery.seed_hosts: 10.1.2.3:9300-9400 ``` Silently ignoring part of a setting like this is trappy. With this change we reject seed host addresses of this form. Closes #40786 Backport of #41404

==== Only a single port may be given for each seed host.
|
|
|
|
In earlier versions you could include a range of ports in entries in the
|
|
`discovery.seed_hosts` list, but {es} used only the first port in the range and
|
|
unexpectedly ignored the rest. For instance if you set `discovery.seed_hosts:
|
|
"10.11.12.13:9300-9310"` then {es} would only use `10.11.12.13:9300` for
|
|
discovery. Seed host addresses containing port ranges are now rejected.
