Jingcheng Du commented on HBASE-12332:
--------------------------------------
Do we need to do this for snapshot?
Actually in the mob, the hfilelinks are not used in the read path. The Mob has
four candidate paths in reading after the snapshot ( mob working, mob archive,
source mob working and source mob archive), these paths are known without
parsing the hfilelink. So is it necessary to detour through the hfilelink?
One more thing is HFileLink can be only parsed its name to a hbase
working/archive dir, it's a new problem to let it parse the file name to a mob
dir.
Please advise. Thanks.
> [mob] use filelink instad of retry when resolving an hfilelink.

> in the snapshot code, hmobstore was modified to traverse an hfile link to a
> mob. Ideally this should use the transparent filelink code to read the data.
> Also there will likely be some issues with the mob file cache with these
> links.
