Creating new hfile links also creates "back references" for GC. > These back references are dangling since the restore location is outside the > root dir, and requires a WRITE permission to the root dir (as opposed to just > READ permission) to be able to run the MR-over-snapshot job. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
