Job with only maptasks and map output still in local disk?

[xeonmailinglist]

Hi,

I noticed that when we have a mapreduce job with no reduce tasks, YARN 
saves the map output is the HDFS. I want that the job still save the map 
output in the local disk.

In YARN, is it possible to have a mapreduce job that only executes map 
tasks (no reduce tasks to execute), and that the map tasks still save 
the map output in the local disk?

Thanks,
