-----------------------------------
Summary: 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: 1.17.0, 1.16.0, 1.15.0, 1.14.0, 1.13.0, 1.11.1, 1.12.0,
1.11.0, 1.10.1, 1.10.0, 1.9.0, 1.17.1
Reporter: Alexey Serbin
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
