terry zhang updated HBASE-9214:
-------------------------------

    Description: 
Today I meet a issue during restore snapshot. It can be reproduce in step below:

1. Table t1 create a Snapshot s1 successfully
2. region r1 in t1 split 
3. CatalogJanitor Chore begin to work and found daughter  do not have reference , so r1 can be deleted
4. restore snapshot s1 . RestoreSnapshotHelper add region r1 to meta table
5.  CatalogJanitor delete r1 region info in meta which RestoreSnapshotHelper just inserted .
6. restore snapshot finished.

Then we can found there is a hole in t1 after restore snapshot. Data loss.
