> Currently the postBulkLoadHFile() hook notifies the locations of bulk loaded hfiles.
> However, if bulk load fails after hfile is moved to region directory but before postBulkLoadHFile()
hook is called, there is no way for pluggable components (replication - see HBASE-17290, backup
/ restore) to know which hfile(s) have been moved to region directory.
> Even if postBulkLoadHFile() is called in finally block, the write (to backup table or
zookeeper) issued from postBulkLoadHFile() may fail, ending up with same situation.
> This issue adds a preCommitStoreFile() hook which notifies path of to be committed hfile
before bulk loaded hfile is moved to region directory.
> With preCommitStoreFile() hook, write (to backup table or zookeeper) can be issued before
the movement of hfile.
> If write fails, IOException would make bulk load fail, not leaving hfile in region directory.
