          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.
          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'
        EOF
      end
