> Consider the catastrophic loss of the namenode.
> Assuming you have a previous snapshot, you can recover the namenode using another node back to that snapshot.
> However, the most recently deleted files will show as corrupt, because the slightly older state will point to blocks that are now gone.
> If the gc delayed file collection for a period of time longer than the age of a snapshot, accumulo could be recovered with the snapshot.
