> It's quite funny and simultaneously very annoying that the {{kudu table copy}} CLI tool crashes on malformed input for its {{\-\-predicates}} flag.
> When encountering an invalid input from a user, the tool should at least:
>  * not crash, but exit gracefully returning non-zero exit code
>  * provide actionable error message to the user, so they are able to fix typos/mistakes and run the tool again, eventually achieving the desired result
