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

I think I am stuck on understanding:

{quote}
It completely bypasses the whitelist and so there is no way for a task to not have HADOOP_CONF_DIR
set. 
{quote}

White list is used by container-executor, which resides in host, and not docker container.
 How is the by pass happened?

> Currently, {{HADOOP_CONF_DIR}} is being put into the task environment whether it's set
by the user or not. It completely bypasses the whitelist and so there is no way for a task
to not have {{HADOOP_CONF_DIR}} set. This causes problems in the Docker use case where Docker
containers will set up their own environment and have their own {{HADOOP_CONF_DIR}} preset
in the image itself.
