>             Project: Mesos
>          Issue Type: Bug
>          Components: docker
>    Affects Versions: 0.25.0
>            Reporter: Martin Tapp
>            Assignee: Shuai Lin
>            Priority: Minor
>              Labels: containerizer

> Note: Affects 0.26 and 0.27.
> The Jupyter Docker all-spark-notebook uses equal sign ('=') in Docker ENV declarations (for instance, https://github.com/jupyter/docker-stacks/blob/master/all-spark-notebook/Dockerfile#L51).
> This causes a mesos Unexpected Env format for 'ContainerConfig.Env' error.
> The problem is the tokenization code at https://github.com/apache/mesos/blob/21e080c5ae6ef03556c7a2b588e034a916c7a05a/src/docker/docker.cpp#L386 which needs to only look at the first equal sign. Docker ENV declarations can also be empty.
