I build mesos-1.0.0-rc2 with network isolator. 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? My OS is centos 7.2. Thanks for any reply [😊] .
