Subject [jira] [Commented] (YARN-7677) HADOOP_CONF_DIR should not be automatically put in task environment
Date Wed, 20 Dec 2017 19:17:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7677?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16298946#comment-16298946

Eric Badger commented on YARN-7677:
-----------------------------------

Linking YARN-3611 since this is related to Docker development. Not putting it as a subtask,
however, because this JIRA has impacts outside of Docker.

> 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.
