             Summary: [ergonomics] add shell,API to "reshape" a table
                 Key: HBASE-13103
                 URL: https://issues.apache.org/jira/browse/HBASE-13103
             Project: HBase
          Issue Type: Brainstorming
          Components: Usability
            Reporter: Nick Dimiduk


Often enough, folks miss-judge split points or otherwise end up with a suboptimal number of regions. We should have an automated, reliable way to "reshape" or "balance" a table's region boundaries. This would be for tables that contain existing data. This might look like:

{noformat}
Admin#reshapeTable(TableName, int numSplits);
{noformat}

or from the shell:

{noformat}
> reshape TABLE, numSplits
{noformat}
