                 Key: HBASE-4321
                 URL: https://issues.apache.org/jira/browse/HBASE-4321
             Project: HBase
          Issue Type: Improvement
            Reporter: Jonathan Hsieh


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).
