Tuning ApplicationMaster container size

I am running a high volume of jobs that have very few mappers and reducers.

The per-job overhead of 1 AM container is taking up a large percentage of
the resources used per job, so I want to make the AM container smaller.

What is the smallest amount of memory that I can allocate to the AM
container?

Thanks,
Benson
