Jerry He commented on HBASE-10615:
----------------------------------
bq. A config parameter will probably be helpful if the bulk load tool itself
can or wants to 'resolve' the reference/link.
Then it will be good to give user an option to 'skip' or 'resolve'.
Now it is more like the only option is to 'skip'.
Or 'error', which doesn't make much meaningful sense.

> There is use base that the source of hfiles for LoadIncrementalHFiles can be
> a FileSystem copy-out/backup of HBase table or archive hfiles. For example,
> 1. Copy-out of hbase.rootdir, table dir, region dir (after disable) or
> archive dir.
> 2. ExportSnapshot
> It is possible that there are reference files in the family dir in these
> cases.
> We have such use cases, where trying to load back into HBase, we'll get
> {code}
