> In HADOOP-3581, we are discussing how to prevent memory intensive tasks from 
> affecting Hadoop daemons and other tasks running on a node. A related 
> requirement is that users be provided an ability to run jobs which are memory 
> intensive. The system must provide enough knobs to allow such jobs to be run 
> while still maintaining the requirements of HADOOP-3581.
