> MRV2 currently does not take reduce disk usage into account when trying to schedule a
container.  For feature parity with the original map reduce it should be extended to allow
for disk space requests within containers along with RAM requests.  We then also need to port
MAPREDUCE-2324 to the scheduler to allow it to avoid starvation of containers that might never
get the resources that they need.
