-------------------------------------------------------------
[~cebe] The commit you mention makes it possible to have - or -- prefixed
arguments for the jobs. As of this change, everything behind the job jar file
is treated as arguments for the jar.
{{./flink run -c classpath job.jar}} sets the class of the job.jar to start
execution.
{{./flink run job.jar -c classpath}} sets the arguments for job.jar to "-c" and
"classpath"
Currently, the parser stops if it finds a non-option (argument not prefixed
with - or --) after "run". That way, you cannot accidentally set options of the
flink command line tool with your job's arguments. In the above example, if the
two commands were identical and if your program had the argument -c, you would
also change the -c option of the flink command line tool which would overwrite
your job's class entry point and lead to a failed submission of the job.
Thus, I suggest to adapt the help notice to make it clear where the flink
command line tool options should go.

Currently, the parser stops if it finds a non-option (argument not prefixed
with - or --) after "run". That way, you cannot accidentally set options of the
flink command line tool with your job's arguments. Imagine, your program had
the argument -m. If the above two examples were equivalent, you would also
change the -m flag of the flink command line tool which would overwrite the job
manager url and lead to a failed submission of the job.
Thus, I suggest to adapt the help notice to make it clear where the flink
command line tool options should go.
