Dustin Cote created MAPREDUCE-6604:
--------------------------------------
Summary: Show quoting examples that do not work in streaming docs
Key: MAPREDUCE-6604
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6604
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: documentation
Reporter: Dustin Cote
Priority: Minor
The hadoop streaming docs [here|https://wiki.apache.org/hadoop/HadoopStreaming]
should be improved to include examples where "complicated quoting is can
introduce bugs". The line including this text should read something like:
{quote}
The "-file shellMapper.sh" part isn't entirely necessary. You can simply use a
clause like "-mapper 'sed | grep | awk'" or some such but complicated quoting
can introduce bugs. As an example, "-mapper 'grep "text"'" will not work.
Wrapping the job in a shell script eliminates some of these issues, but quoting
should be avoided where possible.
