Subject [jira] [Updated] (YARN-944) App failed with container launch failed even though container started
Date Mon, 29 Jul 2013 17:43:50 GMT

     [ https://issues.apache.org/jira/browse/YARN-944?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jian He updated YARN-944:

    Attachment: YARN-944.patch

Today when MapReduce launches a container, Container errors are redirected to syserr file
under container log directory, we are not able to view that in NM log. In case of container-launch
error(the error after user process is launched), users now will always see ShellExitCodeException
in NM log, and the detailed message can be retrieved from container log in web UI. YARN-814
fixed the case that the error before user process is launched will be logged both in NM log
and container log.

For other applications on YARN that are not redirecting stderr, user can see the container
errors both in NM log and container log.

Uploaded a patch to update the logging error message.
