Yun Tang commented on FLINK-26354:
----------------------------------
Since the latest version of commons-cli is 1.5.0, which is what we already used
in Flink. And it must have a short option key while the long option key could
be optional. And FLINK-22701 actually suffers from this problem due to short
option key conflicts. Maybe we could change the dependent library in
Flink-1.16. For current solution, I prefer [~knaufk]'s idea, maybe we could
introduce the short option key such 'rm' for the long option key 'restoreMode'.
> "-restoreMode" should be "--restoreMode" and should have a shorthand
