--------------------------------

Integrated in Hadoop-Common-trunk #590 (See [https://hudson.apache.org/hudson/job/Hadoop-Common-trunk/590/])
    HADOOP-6812. Change documentation for correct placement of configuration variables: mapreduce.reduce.input.buffer.percent,
mapreduce.task.io.sort.factor, mapreduce.task.io.sort.mb. Contributed by Chris Douglas.
