Reducer should start faster for smaller jobs
--------------------------------------------
Key: MAPREDUCE-1463
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1463
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: contrib/fair-share
Reporter: Scott Chen
Assignee: Scott Chen
Our users often complain about the slowness of smaller ad-hoc jobs.
The overhead to wait for the reducers to start in this case is significant.
It will be good if we can start the reducer sooner in this case.
