RegionSplitter : Utility class for manual region splitting
----------------------------------------------------------

                 Key: HBASE-3448
                 URL: https://issues.apache.org/jira/browse/HBASE-3448
             Project: HBase
          Issue Type: New Feature
          Components: client, scripts, util
            Reporter: Nicolas Spiegelberg
            Assignee: Nicolas Spiegelberg
            Priority: Minor
             Fix For: 0.90.1


For certain use cases, there are a number of advantages to manually splitting regions instead
of having the HBase split code determine this for you automatically.  There are currently
some API additions to HBaseAdmin and HTable that allow you to manually split on a small scale.
 This JIRA is about importing a RegionSplitter utility program to help pre-split and perform
rolling splits on a live table when needed.  Will also add documentation to answer common
questions about why you would pre-split.
