I would like to reiterate that this is a major issue, please fix this as soon
as possible.
> Docker environment variables must be able to contain the equal sign
> -------------------------------------------------------------------

> Key: MESOS-4587
> URL: https://issues.apache.org/jira/browse/MESOS-4587
> Project: Mesos
> Issue Type: Bug
> Components: docker
> Affects Versions: 0.25.0
> Reporter: Martin Tapp
> 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.
