> Hbck currently scans through meta one entry at a time, only keeping a
> reference to the previous meta entry. This is insufficient for capturing all
> the possible problems in meta and needs something more to properly identify
> holes, overlaps, duplicate start keys, and otherwise invalid meta entries.
> Ideally, this calculator could also be used online interrogating an existing
> meta (HBASE-4058), and also used to generate a completely new meta offline
> just from regioninfo and in hdfs (HBASE-3505).
