Ravi Prakash updated MAPREDUCE-6220:
    Resolution: Won't Fix
        Status: Resolved  (was: Patch Available)

Hi YangHao. Hadoop already runs on Windows. What Chris is referring to is https://issues.apache.org/jira/browse/YARN-2139
. I understand changing the partition of your datanodes may 
not be trivial. Do you distribute mapred-site.xml to all your nodemanagers?

@Chris, I think YangHao may have been thinking of putting this option in there for production

I'm going to resolve this as Won't Fix

> System.out is a ugly way to print log, and many times it would do harm to Hadoop cluster.
So we can provide an option to forbid it
