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
Ececution & 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)
