Subject [GitHub] flink issue #2662: [FLINK-4824] [client] CliFrontend shows misleading error ...

    Thanks for the PR @greghogan! Having a custom exception for missing arguments to a user
program is a good approach. However, it requires the author of the program to use the custom
exception. At least, we would have to adapt all the included examples. Additionally, it would
be nice to throw another custom exception when no Flink job was generated during execution
of the jar (which might be because of missing arguments). Currently, we simply throw a `ProgramInvocationException`
which could look like a serious error to the user when merely arguments are missing. 
    
    So +1 but we might do some follow-ups to fully solve the issue.
