Hi, We just merged the unified cgroups isolator. Huge shout out to @haosdent and @qianzhang to make this happen! https://issues.apache.org/jira/browse/MESOS-4697
Just to give you some context. Previously, it's a huge pain to add a new cgroups subsystem to Mesos because it requires creating a new isolator (a lot of code duplication). Now, we merge all the subsystems into one single isolator, that makes adding a new subsystem very easy. More importantly, the new cgroups isolator supports cgroups v2! - Jie
