Suma Shivaprasad resolved YARN-7987. ------------------------------------ Resolution: Won't Fix > Docker container name(--name) needs to be DNS friendly for DNS resolution to > work in user defined networks. > ------------------------------------------------------------------------------------------------------------ > > Key: YARN-7987 > URL: https://issues.apache.org/jira/browse/YARN-7987 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Suma Shivaprasad > Assignee: Suma Shivaprasad > Priority: Major > > User defined networks like overlays support DNS resolution through Docker > Embedded DNS which needs the container name (–name parameter value in docker > run) to be a FQDN for container names to be resolved - Please refer > documentation > [https://docs.docker.com/v17.09/engine/userguide/networking/configure-dns/] > However Yarn sets the container name to the container's id which is not DNS > friendly(eg: container_e26_1519402686002_0035_01_000003) and is not a FQDN. > The proposal is to set a FQDN(eg: > ctr-e26-1519402686002-0035-01-000003.domain-name) as the docker container's > name for containers to be able to communicate to each other via hostnames in > user defined networks like overlays, bridges etc. The domain name will be > picked up from the YARN DNS registry configuration > (hadoop.registry.dns.domain-name) > > > > > > > > -- 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
