Shane Kumpf reassigned YARN-7916: --------------------------------- Assignee: Shane Kumpf > Remove call to docker logs on failure in container-executor > ----------------------------------------------------------- > > Key: YARN-7916 > URL: https://issues.apache.org/jira/browse/YARN-7916 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Shane Kumpf > Assignee: Shane Kumpf > Priority: Major > > If a Docker container fails with a non-zero exit code, container-executor > attempts to run a {{docker logs --tail=250 container_name}} to provide more > details on why the container failed. While the idea is good, the current > implementation will fail for most containers as they are leveraging a launch > script whose output will be redirected to a file. The {{--tail}} option > throws an error if no log output is available for the container, resulting in > the docker logs command returning rc=1 in most cases. > I propose we remove this code from container-executor. Alternative approaches > to handle logging can be explored as part of supporting an image's entrypoint. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
