Mridul Muralidharan created SPARK-23719: -------------------------------------------
Summary: Use correct hostname in non-host networking mode in hadoop 3 docker support Key: SPARK-23719 URL: https://issues.apache.org/jira/browse/SPARK-23719 Project: Spark Issue Type: Improvement Components: Spark Core, YARN Affects Versions: 2.4.0 Reporter: Mridul Muralidharan Hostname (node-id's hostname field) specified by RM in allocated containers is the NM_HOST and not the hostname which will be used by the container when running in docker container executor : the actual container hostname is generated at runtime. Due to this spark executor's are unable to launch in non-host networking mode when leveraging docker support in hadoop 3 - due to bind failures as hostname they are trying to bind to is of the host machine and not the container. We can leverage YARN-7935 to fetch the container's hostname (when available) else fallback to existing mechanism - when running executors. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
