Description
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).
