      Description

      Hourly and Daily rolling should not use more than one reducer and they are currently relying on the default parameter to be correct.

      <property>
      <name>mapred.reduce.tasks</name>
      <value>1</value>
      <description>The default number of reduce tasks per job. Typically set
      to a prime close to the number of available hosts. Ignored when
      mapred.job.tracker is "local".
      </description>
      </property>

      This should be forced within the Rolling class in order to avoid any issue.
