Hadoop 0.20 Docs - backport changes for streaming and m/r tutorial docs
-----------------------------------------------------------------------

                 Key: HADOOP-6328
                 URL: https://issues.apache.org/jira/browse/HADOOP-6328
             Project: Hadoop Common
          Issue Type: Task
          Components: documentation
            Reporter: Corinne Chandel
            Assignee: Amareshwari Sriramadasu
            Priority: Blocker
             Fix For: 0.20.2


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)
