Shane Kumpf created YARN-7916: --------------------------------- Summary: 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
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-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
