Subject [jira] [Updated] (YARN-6550) Capture launch_container.sh logs
Date Wed, 23 Aug 2017 20:44:00 GMT

     [ https://issues.apache.org/jira/browse/YARN-6550?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Suma Shivaprasad updated YARN-6550:
-----------------------------------
    Attachment: YARN-6550.007.patch

The previous patch had  portability issues on Ubuntu. Attaching an updated patch which instead
of retaining stderr and stdout with a tee for the launch_container script, redirects it to
a file. It then reads from the prelaunch.err file and updates container diagnostics with the
error(s) that occurred.

> launch_container.sh which generated by NM will do a bunch of things (like create link,
etc.) while launch a process. No logs captured until {{exec}} is called. We need capture all
failures of launch_container.sh for easier troubleshooting.
