Date Wed, 05 Dec 2012 02:40:57 GMT
Peng Lei created MAPREDUCE-4847:
-----------------------------------

             Summary: Command Parsing in Hadoop Streaming
                 Key: MAPREDUCE-4847
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4847
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: contrib/streaming
            Reporter: Peng Lei


Hadoop streaming parse the mapper and reducer commands by itself, this is not a good choice,
when I write a complex mapper/reducer script inline, such as 'perl -ne ...', it don't work.
An alternative way is to send the command to the shell, simply create new process(sh -c "command_and_args"),
this not also simplize the streaming code, but also improve its capability!
