Jan-Philip Gehrcke created MESOS-6989:
-----------------------------------------

             Summary: Docker executor segfaults in ~MesosExecutorDriver()
                 Key: MESOS-6989
                 URL: https://issues.apache.org/jira/browse/MESOS-6989
             Project: Mesos
          Issue Type: Bug
          Components: docker
            Reporter: Jan-Philip Gehrcke


With the current Mesos master state (commit 42e515bc5c175a318e914d34473016feda4db6ff), the
Docker executor segfaults during shutdown. 

Steps to reproduce:

1) Start master:
{code}
$ ./bin/mesos-master.sh --ip=127.0.0.1 --work_dir=/tmp/jp/mesos
WARNING: Logging before InitGoogleLogging() is written to STDERR

{code}
(note that building it at 13:37 is not part of the repro)

2) Start agent:
{code}
$ ./bin/mesos-slave.sh --containerizers=mesos,docker --master=127.0.0.1:5050 --work_dir=/tmp/jp/mesos
{code}

3) Run {{mesos-execute}} with the Docker containerizer:
{code}
$ ./src/mesos-execute --master=127.0.0.1:5050 --name=testcommand --containerizer=docker --docker_image=debian
--command=env
