> When you run an application the container logs shows a lot of messages for
> the RackResolver:
> 2015-03-10 00:58:30,483 INFO [RMCommunicator Allocator]
> org.apache.hadoop.yarn.util.RackResolver: Resolved node175.example.com to
> /rack15
> A real world example for a large job was generating 20+ messages in 2
> milliseconds during a sustained period of time flooding the logs causing the
> node to run out of disk space.
