Hi [~msingh]
Thanks for working on this. I maybe able to get more details from the design
doc you are going to upload to HDFS-11704, before that becomes to be available,
a few comments/questions
*Constants*
Can we name the schema to {{oz}} instead of {{ozfs}} ? I checked some existing
FS implementations, their schema are like, "oss", "adl", "s3a" etc. none of
them contains "fs" suffix.
*OzoneFileSystem*
1. Since oz FS is initiated per bucket, we need to ensure bucket existence
during the {{initialize}}. But there seems no code to check this.
2. line 84 - 88, question: if a client passes, e.g {{/vol/bucket/ppp}}, as the
URI path to init oz FS, is this a valid configuration or an exception to throw?
3. line 99, line 109: can we move constants "http://"; and "/user" to
{{Constants}} class?
4. Can you implement at least one FS API in {{OzoneFileSystem}} to prove this
is working?
Thank you.
