Jie Yu commented on MESOS-2735:
-------------------------------
1) This matches the existing allocator interface.
2) Slave no longer needs to configure the polling interval. It's up to the
resource estimator to decide when to send estimations.
3) It avoid the potential issue that "estimator::update()" is blocking. Slave
will hang if "estimator::update()" blocks.
> Change the interaction between the slave and the resource estimator from
> polling to pushing

> This will make the semantics more clear. The resource estimator can control
> the speed of sending resources estimation to the slave.
> To avoid cyclic dependency, slave will register a callback with the resource
> estimator and the resource estimator will simply invoke that callback when
> there's a new estimation ready. The callback will be a defer to the slave's
> main event queue.
