          Compact all regions in passed table or pass a region row
          to compact an individual region. You can also compact a single column
          family within a region.
          You can also set compact type, "NORMAL" or "MOB", and default is "NORMAL"
          Examples:
          Compact all regions in a table:
          hbase> compact 'ns1:t1'
          hbase> compact 't1'
          Compact an entire region:
          hbase> compact 'r1'
          Compact only a column family within a region:
          hbase> compact 'r1', 'c1'
          Compact a column family within a table:
          hbase> compact 't1', 'c1'
          Compact table with type "MOB"
          hbase> compact 't1', nil, 'MOB'
          Compact a column family using "MOB" type within a table
          hbase> compact 't1', 'c1', 'MOB'
        EOF
      end

      def command(table_or_region_name, family = nil, type = 'NORMAL')
        admin.compact(table_or_region_name, family, type)
      end
    end
