Subject [jira] [Commented] (YARN-6060) Linux container executor fails to run container on directories mounted as noexec
Date Sat, 07 Jan 2017 01:02:35 GMT

    [ https://issues.apache.org/jira/browse/YARN-6060?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15806353#comment-15806353

Miklos Szegedi commented on YARN-6060:
--------------------------------------

Thank you for the comment, [~aw]. As I said, I agree that noexec should not be set on node
manager directories. That does not mean that, if set Yarn should completely fail and not run
any job. Can you be more specific on this one "huge hole on misconfigured systems"?
