Enis Soztutar resolved HBASE-10859.
-----------------------------------
Resolution: Fixed
Hadoop Flags: Reviewed
Thanks for reviews! I've committed this to hbase-10070.
bq. Nice. Only one question/nit: for these loops, does it make sense/matter to
throw the first exception instead of the last one?
All exceptions are FNFE from the locations of the FileLink. It won't matter
that much whether we are throwing the first or the last.

> The region fails to open for the region replica, because at this time, the
> primary region is performing a compaction. The file is moved to the archive
> directory in between listing of store files and opening those store files
> from the secondary.
> The secondary region should able to deal with this through usage of
> StoreFileInfo and HFile, but since we are reconstructing the StoreFileInfo
> object twice between HStore.openStoreFiles() and createStoreFileAndReader()
> we are getting this exception.
