Subject [jira] [Commented] (YARN-7677) Docker image cannot set HADOOP_CONF_DIR
Date Thu, 15 Feb 2018 15:31:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7677?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16365736#comment-16365736
] 

Jason Lowe commented on YARN-7677:
----------------------------------

That makes sense.  Agreed it is probably safer to leave the CLASSPATH in the batch of user
vars.

 +1 for the latest patch.  I'll commit this later today if there are no objections.

> 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.
