      Description

      When accessing the JMX data via http (http://namenode:50070/jmx) there are a couple of useful fields missing from this bean:

      "name" : "Hadoop:service=NameNode,name=NameNodeInfo",
      "modelerType" : "org.apache.hadoop.hdfs.server.namenode.FSNamesystem",

      Please add the number of blocks and the configured capacity.
