Vladimir Rodionov commented on HBASE-17292:
-------------------------------------------

Yes, add postCommit hook and fix <String, Path>. lgtm after that.

> 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.
> This issue adds a preCommitStoreFile() hook which notifies path of to be committed hfile
before bulk loaded hfile is moved to region directory.
