Commit f80f6e9f5c28cb67148c3e6b1a439e2b2a4dd8ab in kudu's branch
refs/heads/branch-1.17.x from Alexey Serbin
[ https://gitbox.apache.org/repos/asf?p=kudu.git;h=f80f6e9f5 ]
KUDU-3623 do not crash on invalid input for 'kudu table copy'
This patch adds code to handle invalid input for the --predicates flag
of the 'kudu table copy' tool. Now, instead of crashing on any
non-expected input, the tool exists gracefully and reports an actionable
error message. With that, now it's easier to understand what was wrong,
correct typos/mistakes, and re-run the tool again, eventually achieving
the desired goal.
A new test is added to cover the newly introduced functionality.
This is a follow-up to 0afeddf9e530762e0e47beb7428982763715c746.

> 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
