-----------------------------------------

Yep, it would be good to also provide isolation between tasks running on the same agent

> Currently the driver will accept offers from Mesos which have enough ram for the executor
and until its max cores is reached. There is no way to control the required CPU's or disk
for each executor, it would be very useful to be able to apply something similar to spark.mesos.constraints
to resource offers instead of attributes on the offer.
