Aaron Fabbri commented on HADOOP-13448:
---------------------------------------
[~liuml07] can you elaborate on why you prefer S3AFileSystem?
Yes, it is feasible to extract this work because there are no dependencies on
S3A as the code stands today, besides the fact that it happens to live in that
project.
Also from layering perspective, I'd prefer S3A --depends-on> MetadataStore
instead of a circular dependency.
