-----------------------------------
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!
