Zhankun Tang created YARN-6720: ---------------------------------- Summary: Support updating FPGA related constraint node label after FPGA device re-configuration Key: YARN-6720 URL: https://issues.apache.org/jira/browse/YARN-6720 Project: Hadoop YARN Issue Type: Sub-task Components: yarn Reporter: Zhankun Tang
In order to provide a global optimal scheduling for mutable FPGA resource, it seems an easy and direct way to utilize constraint node labels(YARN-3409) instead of extending the global scheduler(YARN-3926) to match both resource count and attributes. The rough idea is that the AM sets the constraint node label expression to request containers on the nodes whose FPGA devices has the matching IP, and then NM resource handler update the node constraint label if there's FPGA device re-configuration. -- 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
