[jira] Created: (HADOOP-6328) Hadoop 0.20 Docs - backport changes for streaming and m/r tutorial docs

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)

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

Corinne, In the generated patch, the complete streaming.xml file is deleted and added again (May be the patch generation was wrong), we might not want to do that. Can you regenerate the patch? Thanks

I have attached new  (separate) patches for the Streaming doc and M/R Tutorial doc.
I have attached Streaming and M/R Tutorial PDF files which show the changes.
Please note - the Streaming doc was completely reorganized and edited - all sections were changed.

Thanks/C
