Weiwei Yang updated YARN-8013: ------------------------------ Summary: Support APP-TAG namespace for allocation tags (was: Support app-tag namespace for allocation tags) > Support APP-TAG namespace for allocation tags > --------------------------------------------- > > Key: YARN-8013 > URL: https://issues.apache.org/jira/browse/YARN-8013 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Weiwei Yang > Assignee: Weiwei Yang > Priority: Major > > YARN-1461 adds *Application Tag* concept to Yarn applications, user is able > to annotate application with multiple tags to classify apps. We can leverage > this to represent a namespace for a certain group of apps. So instead of > calling *app-label*, propose to call it *app-tag*. > A typical use case is, > There are a lot of TF jobs running on Yarn, and some of them are consuming > resources heavily. So we want to limit number of PS on each node for such BIG > players but ignore those SMALL ones. To achieve this, we can do following > steps: > # Add application tag "big-tf" to these big TF jobs > # For each PS request, we add "ps" source tag and map it to constraint > "notin, node, tensorflow/ps" or "cardinality, node, tensorflow/ps, 0, 2" for > finer grained controls. -- 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
