Chris Nauroth updated HADOOP-13448:
-----------------------------------
Attachment: HADOOP-13448-HADOOP-13345.003.patch
I'm attaching patch revision 003. Here is a summary of the changes since last
time:
* Removed the type bounds that would have been dropped due to instantiation
through {{ReflectionUtils#newInstance}}.
* Converted {{MetadataStore}} to an interface instead of an abstract base class.
* Added the methods we discussed to {{DirListingMetadata}}.
* Added {{PathMetadata#toString}}.
* Used {{ConcurrentHashMap}} inside {{DirListingMetadata}} for thread safety.
* Added more pre-condition checks to address a TODO.
* Added a unit test suite to address another TODO.
* Fixed a JavaDoc failure.
* Cleanup for Checkstyle.
> S3Guard: Define MetadataStore interface.
