Steve Loughran commented on HADOOP-9565:
----------------------------------------

also: call it {{ObjectStore}} as that is potentially more widely known/the 
formal name.

> Add a Blobstore interface to add to blobstore FileSystems

>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: fs
>    Affects Versions: 2.0.4-alpha

>            Priority: Minor
>
> We can make the fact that some {{FileSystem}} implementations are really 
> blobstores, with different atomicity and consistency guarantees, by adding a 
> {{Blobstore}} interface to add to them. 
> This could also be a place to add a {{Copy(Path,Path)}} method, assuming that 
> all blobstores implement at server-side copy operation as a substitute for 
> rename.
