Chris Douglas commented on MAPREDUCE-6220:
------------------------------------------
The patch won't work on Windows.
This seems unlikely to solve the problem... users printing lots of messages to
stdout/stderr won't think to suppress the output using an esoteric config knob
before they submit. Until YARN limits disk usage, corralling users to run on
partitions separated from HDFS, etc. will at least limit the damage done by
containers.

> 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
