Subject Re: Viewing hadoop mapper output

A streaming jobs stderr is logged for the task, but its stdout is what is sent to the reducer.
 The simplest way to get it is to turn off the reducers, and then look at the output in HDFS.

Hello,

I want to view the mapper output for a given hadoop streaming jobs (that
runs a shell script). However I am not able to find this in any log files.
Where should I look for this ?

Thanks,
Aishwarya
