I think we would still need a specific implementation for the file based store
tracking that adds the references to the StoreFileTracker registry, so that
when opening the region it knows those are valid files (not uncommitted ones).

IMO the answer is no, no special implementation here. We should implement the
logic upon the StoreFileTracker interface. No matter what the actual
implementation of StoreFileTracker, we always do the same thing. Link store
files, add the store file list to StoreFileTracker, and then record the region
in hbase:meta. The difference here is that, for DefaultStoreFileTracker, we
just do nothing. For file based or region based StoreFileTracker, we need to
insert the store files into our tracking system. If this operation fails, we
just fail the split/merge, there is no problem as we have not recorded the new
regions in hbase:meta yet. And once this is done, then we will record the new
regions in hbase:meta to make them available, and we can make sure that till
now the tracking system has the correct store file list.
Thanks.
