------------------------------------

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.
