> This JIRA addresses issues in the Streaming doc that also require a cross-link to and
update in the M/R Tutorial doc. All changes approved by the reviewing engineer.
> Streaming issues:
> 1.  During the execution of a streaming job, the names of the "mapred" parameters are
transformed. The dots ( . ) become underscores ( _ ).
> Docs affected: streaming and m/r tutorial (new sub-sections added under Task Execution
& Environment section)
> 2. For -files and -archives options, Hadoop now creates symlink with same name as file
(user-defined symlinks, #mysymlink, currently not supported)
> Docs affected:streaming
> 3. Streaming supports streaming command options and generic command options. Generic
options must be placed before streaming options, otherwise command fails.
> Docs affected: streaming (reorganized the streaming doc to make distinctions between
2 sets of command options more clear)
