             Summary: Remove the optional host and webui-port in jobmanager.sh 
and use common args instead
                 Key: FLINK-21619
                 URL: https://issues.apache.org/jira/browse/FLINK-21619
             Project: Flink
          Issue Type: Improvement
          Components: Deployment / Scripts
            Reporter: Yang Wang


Currently, the {{jobmanager.sh}} only have two optional arguments, "host" and 
"webui-port". Actually, the "webui-port" could not work unless we also specify 
the "host".

 

I suggest to remove the two optional arguments and use common args instead, 
just like {{standalone-job.sh}}. After then we could support more options, for 
example, "--host host1", "--webui-port 8081", "-Dxx=yy". It is more flexible 
and easier to use.

 

Before:
{code:java}
Usage: jobmanager.sh ((start|start-foreground) [host] 
[webui-port])|stop|stop-all
{code}
After:
{code:java}
Usage: jobmanager.sh ((start|start-foreground) [args])|stop|stop-all
{code}
