-----------------------------------
Since this ticket will introduce incompatible changes for the script
deployment(jobmanager.sh), I am a little concerned. Actually, I am not sure
about the script compatibility we have promised to our users.
> jobmanager.sh may misinterpret webui-port argument

> Key: FLINK-21038
> URL: https://issues.apache.org/jira/browse/FLINK-21038
> Project: Flink
> Issue Type: Improvement
> Components: Deployment / Scripts
> Affects Versions: 1.9.0
> Reporter: Chesnay Schepler
> Priority: Major
>
> The usage description for {{jobmanager.sh}} is as follows:
> {code}
> Usage: jobmanager.sh ((start|start-foreground) [host]
> [webui-port])|stop|stop-all
> {code}
> It shows both {{host}} and {{webui-port}} as _separate_ optional arguments,
> however we hard-code the positions of these parameters:
> {code}
> STARTSTOP=$1
> HOST=$2 # optional when starting multiple instances
> WEBUIPORT=$3 # optional when starting multiple instances
> {code}
> As such you cannot set the webui.port without also setting some dummy host
> argument.
> I'm wondering whether we could not remove these in favor of dynamic
> properties.
