Shane Kumpf commented on YARN-7677:
-----------------------------------

[~Jim_Brennan], thanks for putting this together. With this patch in, all AM's are failing
to launch with classpath related issue in my dev environment. Still looking into the cause,
but do you have any thoughts?

> 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.
