      Description

      The following configs are in core-default.xml, but are really read by the Secondary Namenode. These should be moved to hdfs-default.xml for consistency.
      <property>
      <name>fs.checkpoint.dir</name>
      <value>${hadoop.tmp.dir}/dfs/namesecondary</value>
      <description>Determines where on the local filesystem the DFS secondary
      name node should store the temporary images to merge.
      If this is a comma-delimited list of directories then the image is
      replicated in all of the directories for redundancy.
      </description>
      </property>

      <property>
      <name>fs.checkpoint.edits.dir</name>
      <value>${fs.checkpoint.dir}</value>
