[jira] [Created] (HBASE-7846) Add support for merging implicit regions in Merge tool

---------------------------------

             Summary: Add support for merging implicit regions in Merge tool
                 Key: HBASE-7846
                 URL: https://issues.apache.org/jira/browse/HBASE-7846
             Project: HBase
          Issue Type: Improvement
          Components: util
            Reporter: Kaufman Ng
            Priority: Minor


Currently org.apache.hadoop.hbase.util.Merge needs 2 region names to be explicitly specified to perform a merge.  This can be cumbersome.
One idea for improvement is to have Merge to figure out all the adjacent regions and perform the merges.  

For example:
regions before merge: row-10, row-20, row-30, row-40, row-50
regions after merge: row-10, row-30, row-50

In the above example, region names of "row-10" and "row-20" are merged to become a new bigger region of "row-10".
