Prabhu Joseph commented on FLINK-31518:
---------------------------------------
Thanks for the pointers. [~vineethNaroju] and I have come up with a patch based
on the above inputs.
{quote}And another one is which one is invoked first, the start of
WebMonitorEndpoint or the creation of high available service?{quote}
High Availability Services {{StandaloneHaServices}} is initialised first with
the configured {{clusterRestEndpointAddress}} which can be a range of ports,
and then the {{RestServerEndpoint}} is started, which has the actual port.
The patch sets the configuration with the rest address and rest port, from
which the {{StandaloneHaServices#getClusterRestEndpointLeaderRetriever}}
retrieves the address and port. Similar ways are used in other places, like the
one for the JobManager RPC Port.
This is the [WIP patch

Please review it and let us know your comments.

> Key: FLINK-31518
> URL: https://issues.apache.org/jira/browse/FLINK-31518
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Configuration, Runtime / REST
> Affects Versions: 1.16.0, 1.17.0, 1.16.1, 1.17.1
> Reporter: Vineeth Naroju
> Priority: Major
>
> {{HighAvailabilityServiceUtils#createHighAvailabilityServices()}} in
> {{HighAvailabilityMode.NONE}} mode uses
> {{HighAvailabilityServiceUtils#getWebMonitorAddress()}} to get web monitor
> address.
> {{HighAvailabilityServiceUtils#getWebMonitorAddress()}} reads only from
> {{rest.port}} in {{flink-conf.yaml}} . If {{rest.port}} is not enabled, then
> it returns {{0}} port number. It should dynamically fetch port number if
> {{rest.port}} is disabled.
