Martijn Visser commented on FLINK-26858:
----------------------------------------
[[email protected]] Looking at your PR, you're adding "And the command
line input instruction is spelled correctly". That still doesn't add a lot of
value for the user, because the user doesn't know what might be wrong in the
instruction. If we really want to add value, we should report what is an
incorrect/not recognized input and report that to the user. That would add
value.
