      Description

      <property>
      <name>mapred.speculative.execution</name>
      <value>true</value>
      <description>If true, then multiple instances of some map tasks may
      be executed in parallel.</description>
      </property>

      This property also controls speculative execution of reduces, however the description field doesn't indicate that.
