Jim Brennan commented on YARN-8027: ----------------------------------- This code was added by [YARN-6804]. [~billie.rinaldi], [~jianh], I don't think we should be setting --hostname when --net=host. Do you agree? > Setting hostname of docker container breaks for --net=host in docker 1.13 > ------------------------------------------------------------------------- > > Key: YARN-8027 > URL: https://issues.apache.org/jira/browse/YARN-8027 > Project: Hadoop YARN > Issue Type: Bug > Components: yarn > Affects Versions: 3.0.0 > Reporter: Jim Brennan > Assignee: Jim Brennan > Priority: Major > > In DockerLinuxContainerRuntime:launchContainer, we are adding the --hostname > argument to the docker run command to set the hostname in the container to > something like: ctr-e84-1520889172376-0001-01-000001. > This does not work when combined with the --net=host command line option in > Docker 1.13.1. It causes multiple failures when the client tries to resolve > the hostname and it fails. > We haven't seen this before because we were using docker 1.12.6 which seems > to ignore --hostname when you are using --net=host. -- 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
