Accessing tasktracker.jsp reserved memory parameters from WebUI via REST API

From the MapR Tasktracker.jsp web interface, there are 3 fields that are of interest to me:

 1. Memory reserved for map-reduce tasks
 2. Default Memory Reserved for map task
 3. Default Memory Reserved for reduce task

I looked through your documentation and was unable to find any of these fields accessible via your RESTful API.  Could you point me in the right direction as to how I can access these fields?

I found something that is close to **Memory reserved for map-reduce tasks** and that is the field: *mapreduce.tasktracker.reserved.physicalmemory.mb* when I perform a `hadoop conf -dump`.  However, the problem with this field is that it is off by a couple hundred megabytes when compared to the tasktracker.jsp page.

Thanks for any help offered.
