Billie Rinaldi commented on YARN-7540: -------------------------------------- +1 for patch 006. This resolves issues with flex and save that I was seeing in earlier patches. I noticed a bug in the ApiServer where it fails to destroy a service that is stopped, but we can address this elsewhere since it is not introduced in this patch. > 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 > Assignee: Eric Yang > Fix For: yarn-native-services > > Attachments: YARN-7540.001.patch, YARN-7540.002.patch, > YARN-7540.003.patch, YARN-7540.004.patch, YARN-7540.005.patch, > YARN-7540.006.patch > > > 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-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
