Inconsistency of agents observed by the local scheduler #41

Closed dcvan24 closed 6 years ago

dcvan24 commented 6 years ago

The local scheduler observes inconsistent agents between different scheduling calls, even the agents are not changed and consistently returned from the calls to the Mesos API. For instance, there are 9 agents up and running in the cluster, but the local scheduler sometimes only observes 1 agent up and running.

The issue is caused mainly because the agent parameter of the scheduler in the custom local scheduler is overridden. The fix does not prevent the custom scheduler from overriding the parameters and causing the issue. Cautions have been added to the abstract class.
