--------------------------------------
Summary: Make verbose mode more user-friendly
Key: HDDS-4160
URL: https://issues.apache.org/jira/browse/HDDS-4160
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Components: Ozone CLI
Reporter: Attila Doroszlai
{{GenericCli}}-based commands have a {{\-\-verbose}} flag, which has two
effects:
# some subcommands print additional details
# stack trace is shown in case of exception
I think (1) is more generally useful, while (2) is geared towards developers.
To avoid making {{--verbose}} commands overwhelming for users in case of
errors, I propose to split these two effects.
Possible solutions:
# multi-level {{--verbose}} mode (allow specifying {{-v}} more than once to get
more details)
# introduce a new flag to enable the stack trace
# only print the stack trace if exception message is not meaningful (eg. empty
or {{"null"}})
