Arun Suresh reassigned YARN-5255: --------------------------------- Assignee: Arun Suresh > Move ResourceRequest expansion for Delay Scheduling to the Scheduler > -------------------------------------------------------------------- > > Key: YARN-5255 > URL: https://issues.apache.org/jira/browse/YARN-5255 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Arun Suresh > Assignee: Arun Suresh > > YARN-4879 proposes to enhance the Allocate Request by introducing a way to > explicitly identify a ResourceRequest explicitly > Currently, if relaxLocality == true, a Node specific request is expanded to > rack and *ANY* request by the {{AMRMClient}} before being sent to the > Scheduler. The requires the 3 copies to perform locality specific delay > scheduling. > It would be better to perform the expansion in the Scheduler itself, rather > than the client, since: > # The expansion is not really specified in the ApplicationMasterProtocol, a > non-java client will have to duplicate the expansion logic. > # Refactor out a lot of unnecessary code in the {{AMRMClientImpl}} -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
