             Summary: max_executors_per_agent does not take effect on mesos docker executor
                 Key: MESOS-5885
                 URL: https://issues.apache.org/jira/browse/MESOS-5885
             Project: Mesos
          Issue Type: Bug
          Components: master
    Affects Versions: 1.0.0
         Environment: centos 7.2
            Reporter: Qi Feng


I build mesos-1.0.0-rc2 with network isolator in centos 7.2. And try to set max_executors_per_agent=10 to test if docker task would be limited in 10 on every mesos agent. In fact, my case is launching 40 tasks (0.1core 0.1M mem each) on three different agent machine, and both agent launched more than 10 tasks.

I found mesos master hold executor data in a haspmap, and the key is ExecutorID.
https://github.com/apache/mesos/blob/1.0.x/src/master/master.hpp#L306
https://github.com/apache/mesos/blob/1.0.x/src/master/master.cpp#L5747

Then I get state.json from mesos master to looking for any executor information. Then I found executer_id is empty string in taskInfo json. Is there any relation between the empty executor id and max_executors_per_agent issue?
