Pieter Reuse updated HADOOP-9565:
---------------------------------
Attachment: HADOOP-9565-007.patch
Uploaded patch version 7:
* Renamed UnsatisfiedSemanticsException to UnsatisfiedFeatureException
* Renamed ObjectStoreFeatures to ObjectStoreFeature and changed to an
enum-based approach
* added style improvements to FileOutputCommitter, since we're changing a lot
of lines throughout the class. Makes this patch prone to become non-applicable
when other patches change this class.
Chris, thanks for pointing out Steve will be enjoying a well earned break the
coming weeks. We will have patience w.r.t. his response.

> 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.
