[jira] [Created] (MESOS-923) Containerizers should persist their own recovery state.

Ian Downes created MESOS-923:
--------------------------------

             Summary: Containerizers should persist their own recovery state.
                 Key: MESOS-923
                 URL: https://issues.apache.org/jira/browse/MESOS-923
             Project: Mesos
          Issue Type: Improvement
          Components: isolation
            Reporter: Ian Downes
             Fix For: 0.17.0


In the current containerizer refactor (and previous process_isolator and cgroups_isolator) the forked executor pid is persisted by the MesosContainerizer but recovered with the rest of the slave state. This coupling is undesirable as containerizer implementations may or may not use the pid for recovery and may require additional, specific state for recovery.

Instead each containerizer implementation should manage persistence of whatever state they require for recovery.
