Description

When a table exists and is in a disabled state, hbase supports to restore by the snapshot of this table.

In this scenario, hbase would create a failsafe snapshot for this disabled table, and hbase would rollback by this failsafe snapshot when fail to restore.

However on hbase cluster, the failsafe snapshot still exists after rollback successfully by failsafe snapshot.

I think when restore failed by table snapshot but rollback successfully by failsafe snapshot, this failsafe snapshot should be deleted.
