----------------------------------

             Summary: Docker containerizer does not set MESOS_DIRECTORY
                 Key: MESOS-2612
                 URL: https://issues.apache.org/jira/browse/MESOS-2612
             Project: Mesos
          Issue Type: Bug
          Components: containerization, docker, slave
    Affects Versions: 0.22.0
            Reporter: Tom Arnfeld


The {{MESOS_DIRECTORY}} environment variable can be used to get the path to the working directory of the task/executor, aka the sandbox directory. However, a differently named environment variable is used in the Docker containerizer, which is inconsistent with the mesos containerizer and the external containerizer.

The variable {{MESOS_DIRECTORY}} is actually set in the containerizer utils and is shared code, however the call to this in the docker code seems to be wrapped in an if() https://github.com/apache/mesos/blob/00318fc1b30fc0961c2dfa4d934c37866577d801/src/slave/containerizer/docker.hpp#L353-L361.
