> 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.
