--task_index=1 > {code} > This is a bit cumbersome to orchestrate via Distributed Shell, or YARN > services launch_command. In addition, the dynamic parameters do not work > with YARN flex command. This is the classic pain point for application > developer attempt to automate system environment settings as parameter to end > user application. > It would be great if YARN Docker integration can provide a simple option to > expose hostnames of the yarn service via a mounted file. The file content > gets updated when flex command is performed. This allows application > developer to consume system environment settings via a standard interface. > It is like /proc/devices for Linux, but for Hadoop. This may involve > updating a file in distributed cache, and allow mounting of the file via > container-executor. -- 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
