> We notice many HDFS migration cases which translate the first level directory 
> names to Ozone volume names.
> However, some characters in the name of directory are +compliant with POSIX+ 
> convention, but are +not compliant with S3+ naming rule, such as 
> {*}underscore{*}.
> Thus the original HDFS path which contains *underscore* _character are not 
> allowed to put into Ozone because by default Ozone's path validation is same 
> as S3. For such users, this proposal wish to provide a way that when the user 
> gives a flag while creating the volume via Ozone CLI, Ozone will allow 
> *underscore*_ only for such volumes. The idea is it'd be user's choice 
> whether to create a non-s3 naming compliant volume or not.  Ozone will keep 
> equally supporting both kinds of volume. For pure file system back ground 
> users, they may want to go ahead to use this flag.
