Elek, Marton commented on HDDS-453:
-----------------------------------
bq. An other alternative is to copy out the specific parsing logic for only
those options that make sense for OM/SCM from GenericOptionsParser, and then
using picocli to handle them.
I would prefer to do this one, sooner or later. I think the error handling of
GenericOptionsParser problematic and picocli provides better user experience.
S3Gatway implemented to use picocli/GenericCli, so we need to add the missing
arguments anyway (but only a subset of them as we don't need all the mapreduce
specific flags...)
HDDS-1192 has already opened to support the "-conf" flag.
