-----------------------------
    Fix Version/s:     (was: 3.0.1)

> 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.
