stack updated HBASE-6610:
-------------------------
Resolution: Fixed
Release Note: Adds a 'HardLink', an hfile proxy that tolerates files being
moved from original location out to archive; it will find and serve the data
whichever location the file happens to be in.
Hadoop Flags: Reviewed
Status: Resolved (was: Patch Available)
Committed to trunk. Nice one Matteo. I made a pass at a release note. Feel
free to improve. Nice reviewing Jesse (I think this one of the most reviewed
patches in hbase history -- good going lads)

> To avoid copying data during restore snapshot we need to introduce an HFile
> Link that allows to reference a file that can be in the original path
> (/hbase/table/region/cf/hfile) or, if the file is archived, in the archive
> directory (/hbase/.archive/table/region/cf/hfile).
