  Remove decommission marker from a region server to allow regions assignments.

  Optionally, load regions onto the server by passing a list of encoded region names.
  NOTE: Region loading is asynchronous.

  Examples:
    hbase> recommission_regionserver 'server'
    hbase> recommission_regionserver 'server,port'
    hbase> recommission_regionserver 'server,port,starttime'
    hbase> recommission_regionserver 'server,port,starttime', ['encoded_region_name1', 'encoded_region_name1']
EOF
      end

      def command(server_name, encoded_region_names = [])
        admin.recommission_regionserver(server_name, encoded_region_names)
      end
    end
  end
