Gen Luo commented on FLINK-30943:
---------------------------------

Hiding sensitive configurations is already supported if the key and its value 
are connected. The jira tries to hidden the value who's separated from its key.
However I also agree that we don't need to support such cases. Users can easily 
change the argument list to the supported format. And the neighboring argument 
may doesn't have any relation, in which case this feature may cause users 
confused.

> When a job is submitted from the command line, log prints jvm options and 
> application dynamic parameters. 
> now only dynamic parameters (`-Dxx=yy`) are masked, but the key-value 
> separation parameter (`--key value`) is not masked.
