Review request for mesos and Vinod Kone.


i'll shepherd this -- vinod.

Repository: mesos-git


This isolator only creates the perf_event cgroup and places the executor into the cgroup;
no performance statistics are gathered/exported.

NOTE: The recover() as implemented is "non-strict"; it will happily recover containers even
if they don't have a perf_event cgroup present. This permits restarting the slave to add this
isolator. Existing containers will not be isolated. New containers will be isolated.


  src/ 4a3f2e12643a1f02284587ebcbe9374f416b3d60 
  src/slave/containerizer/isolators/cgroups/perf_event.hpp PRE-CREATION 
  src/slave/containerizer/isolators/cgroups/perf_event.cpp PRE-CREATION 



Manually tested.

Our current testing code does not easily permit testing different combinations of isolators
for the MesosContainerizer.
