Subject [jira] [Commented] (HBASE-12673) Add a UT to read mob file when the mob hfile moving from the mob dir to the archive dir

Jiajia Li commented on HBASE-12673:
-----------------------------------

hi, [~jon@cloudera.com], sorry I can't understand the meaning of  "it is starting to be used
in other places and needs to be done". Do you means it used in the SnapshotInfo tool? The
process of reading MOB cell is through getting the filename from the reference cell, then
open the file through the possible locations. The reference cell in hbase is only a filename,
so I think hfilelink can't be used in reading mob cell.
