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