Subject Streaming jar creates only 1 reducer
Date Fri, 21 Oct 2011 21:59:39 GMT
Hi,
Does streaming jar create 1 reducer by default ? We have reduce tasks per
task tracker configured to be more than 1 but my job has about 150 mappers
and only 1 reducer:

reducer.py basically just reads the line and prints it.

Why doesn't streaming.jar invokes multiple reducers for this case ?

Thanks,
-JJ
