Eric Yang created YARN-7540: ------------------------------- Summary: Convert yarn app cli to call yarn api services Key: YARN-7540 URL: https://issues.apache.org/jira/browse/YARN-7540 Project: Hadoop YARN Issue Type: Sub-task Reporter: Eric Yang
For YARN docker application to launch through CLI, it works differently from launching through REST API. All application launched through REST API is currently stored in yarn user HDFS home directory. Application managed through CLI are stored into individual user's HDFS home directory. For consistency, we want to have yarn app cli to interact with API service to manage applications. For performance reason, it is easier to implement list all applications from one user's home directory instead of crawling all user's home directories. For security reason, it is safer to access only one user home directory instead of all users. Given the reasons above, the proposal is to change how {{yarn app -launch}}, {{yarn app -list}} and {{yarn app -destroy}} work. Instead of calling HDFS API and RM API to launch containers, CLI will be converted to call API service REST API resides in RM. RM perform the persist and operations to launch the actual application. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
