Hi all, In https://issues.apache.org/jira/browse/MESOS-8140, I'm proposing that we clear the MESOS_EXECUTOR_AUTHENTICATION_TOKEN environment variable immediately after consuming it in the built-in executors. This protects it from observation by other tasks in the same PID namespace, however I wanted to verify that no-one currently has a use case that depends on this. Currently, the token is inherited to the environment of tasks running under the command executor (i.e. not to task group tasks).
Eventually we would add a formal API for tasks to access the executor token in MESOS-8018. thanks, James
