-----------------------------------------
Thanks for raising the Jira for this - I guess the with any CLI tool having
--predicates flag namely kudu table copy, kudu table scan, kudu perf table_scan.
> The 'kudu table copy' CLI tool crashes on invalid user input for filter
> predicates

> Key: KUDU-3623
> URL: https://issues.apache.org/jira/browse/KUDU-3623
> Project: Kudu
> Issue Type: Bug
> Components: CLI
> Affects Versions: 1.9.0, 1.10.0, 1.10.1, 1.11.0, 1.12.0, 1.11.1, 1.13.0,
> 1.14.0, 1.15.0, 1.16.0, 1.17.0, 1.17.1
> Reporter: Alexey Serbin
> Priority: Major
>
> 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
