Barak Shechter updated MESOS-3137:
----------------------------------
Description:
We are currently experiencing long startup times because we are requesting CPU
based on what tasks' during the normal course of operation.
As a workaround, we have given our tasks a longer grace period and more CPU so
that they start up in a more reasonable amount of time and are not terminated
as quickly. Unfortunately, this leads to underutilization of resources because
our applications don't require the higher cpu fraction after they've
bootstrapped.
We would like to be able to specify a higher CPU allotment for task startup
which can then be reduced for steady state operation of the task.
