setting io.sort.factor does not have effect? --------------------------------------------
Key: HADOOP-1002
URL: https://issues.apache.org/jira/browse/HADOOP-1002
Project: Hadoop
Issue Type: Bug
Reporter: Runping Qi
I have a m/r job with 84000 mappers.
I set io.sort.factor to 200.
The reducers still generates 800+ merged files, not 400+ I expected.
