Suma Shivaprasad commented on YARN-7935: ---------------------------------------- This is no longer needed since the container's hostname, IP and additional information could be obtained via YARN-8659 by Spark or other AMs which need this information. > Expose container's hostname to applications running within the docker > container > ------------------------------------------------------------------------------- > > Key: YARN-7935 > URL: https://issues.apache.org/jira/browse/YARN-7935 > Project: Hadoop YARN > Issue Type: Sub-task > Components: yarn > Reporter: Suma Shivaprasad > Assignee: Suma Shivaprasad > Priority: Major > Labels: Docker > Attachments: YARN-7935.1.patch, YARN-7935.2.patch, YARN-7935.3.patch, > YARN-7935.4.patch > > > Some applications have a need to bind to the container's hostname (like > Spark) which is different from the NodeManager's hostname(NM_HOST which is > available as an env during container launch) when launched through Docker > runtime. The container's hostname can be exposed to applications via an env > CONTAINER_HOSTNAME. Another potential candidate is the container's IP but > this can be addressed in a separate jira. -- 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
