Description

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".
