Summary:
The documentation page provides only Windows-centric examples for Hadoop Streaming activities, specifically referencing '.exe' files (e.g., MyMapper.exe, MyReducer.exe) as mapper and reducer executables. There are no examples or mentions of Linux/Unix-style scripts (e.g., Python, Bash, or shell scripts), which are more common in Hadoop environments. This may mislead users into thinking only Windows executables are supported or recommended.
Recommendations:
- Add Linux/Unix-based examples for mapper and reducer scripts, such as Python (.py), Bash (.sh), or other common script types used in Hadoop Streaming.
- Clarify in the documentation that both Windows executables and Linux/Unix scripts are supported, if applicable.
- Provide at least one example using a non-Windows executable (e.g., 'MyMapper.py', 'MyReducer.sh') in the JSON sample and file paths.
- Explicitly mention any platform requirements or limitations for the mapper/reducer programs.
- Consider reordering or balancing examples to reflect the prevalence of Linux in Hadoop environments.
