Hi,
TL;DR Executors will no longer inherit environment variables from the agent
by default in 0.30.
Currently, executors are inheriting environment variables form the agent in
mesos containerizer by default. This is an unfortunate legacy behavior and
is insecure. If you do have environment variables that you want to pass to
the executors, you can set it explicitly by using the
`--executor_environment_variables` agent flag.
Starting from 0.30, we will no longer allow executors to inherit
environment variables from the agent. In other words,
`--executor_environment_variables` will be set to “{}” by default. If you
do depend on the original behavior, please set
`--executor_environment_variables` flag explicitly.
Let us know if you have any comments or concerns.
Thanks,
Gilbert
