Ritesh H Shukla commented on HDDS-7585:
---------------------------------------
Another alternative might be to provide a chroot-like functionality to the
client. This way, the additional volume, and bucket are not part of the
ofs://<service>//<path> (vs ofs://<service>/vol/bucket/<path>).
> Allow Ozone bucket to use non-S3-compliance naming rule
> -------------------------------------------------------
>
> Key: HDDS-7585
> URL: https://issues.apache.org/jira/browse/HDDS-7585
> Project: Apache Ozone
> Issue Type: Improvement
> Components: Ozone CLI, Ozone Filesystem, Ozone Manager
> Reporter: Dave Teng
> Priority: Major
>
> We notice many HDFS migration cases which translate the second level
> directory names to Ozone bucket 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 '' 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 bucket via Ozone CLI (not from S3 interface), Ozone will
> allow '' only for such buckets. The idea is it'd be user's choice whether to
> create a non-s3 compliant bucket path or not. Ozone will keep equally
> supporting both OFS and S3 interfaces. For pure file system back ground
> users, they may want to go ahead with this flag by having the awareness of
> that they may not be able to access the bucket through S3 interface.
>
> This Jira is an umbrella ticket that makes Ozone compatible with these two
> types of naming convention, both POSIX and S3, to enable the HDFS to Ozone
> migration with non s3 compliant paths.
>
> (ps:
> - This proposal wouldn't change the default behavior of S3 bucket naming
> semantic in Ozone.
> - The documentation for new flag will be provided! )
