      Description

      Doc changes added to the Hadoop/mapreduce/trunk (for Hadoop 0.21 release) need to be backported to Hadoop-0.20 branch (for Hadoop 0.20.2 release).

      Doc files affected:
      > streaming.xml
      > mapred_tutorial.xml

      Changes include:
      1. During the execution of a streaming job, the names of the "mapred" parameters are transformed. The dots ( . ) become underscores ( _ ). – (affects streaming doc and m/r tutorial doc)

      2. For -files and -archives options, Hadoop now creates symlink with same name as file (user-defined symlinks, #mysymlink, currently not supported) – (affects streaming doc)

      3. Streaming supports streaming command options and generic command options. Generic options must be placed before streaming options, otherwise command fails. – (affects streaming doc)
