      Description

      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.
