> During snapshot MOB regions are treated like any other region. When a snapshot is taken and hfile references are collected a StoreFileTracker is created to get the current active hfile list. But the MOB region stores are not tracked so an empty list is returned, resulting in a broken snapshot. When this snapshot is cloned the resulting table will have no MOB files or references.
