Suma Shivaprasad created YARN-7935: -------------------------------------- Summary: 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
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-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
