             Summary: HADOOP_CONF_DIR should not be automatically put in task environment
                 Key: YARN-7677
                 URL: https://issues.apache.org/jira/browse/YARN-7677
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Eric Badger
            Assignee: Eric Badger


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.
